Blender3D - Creating a Hologram Earth with Blender 2.93 Geometry Nodes (TUTORIAL)

Hi guys welcome to my channel i'm Chong today i'm going to share with you how to create a horogram earth in blender 3d 2.93 before we dive into Blender let me break down what we are going to do in this tutorial this scene is actually formed by four different basic elements so first we are going to draw the four basic elements here then we are going to make the basic shape of the earth by using geometry nodes and next we are going to scatter the hexagon around the earth then add the counter numbers and we actually need to use animation node to animate the numbers later so if you haven't downloaded it please download it at animation node website and then last we are going to make some color correction for the final render using blender compositor so without further ado let's get started first we are going to draw the four basic element so select the point light and delete it select the cube press shift d to duplicate the cube and then press y to move it beside select both of the cube then press G and then press Y to move it beside press shift A and add the text press tab to go into edit mode and type 0.00 we are going to animate it later so just put a random number for now you can put any number you like then press tab again to exit the edit mode and then now we want to change the font so go to the object data properties under the font section click the folder button to load the font so select the “Aero Matics” font i'm going to use this by the way you can choose other font you like but i'm going to use aromatic font for this tutorial i have put the download link in the description below so if you need it you can download it press g and then press y to move it beside and then next we are going to add a hexagon so press shift a go to mesh and add a circle change the vertices to 6 right click the hexagon and convert it to curve go to object data properties here under under the geometry section go to bevel and change the depth to 0.01 then right click and convert it to mesh again and then press shift A again to add a cylinder change the vertices to 18 the radius to 0.007 and the depth to 5 and now actually i want to make the top of the cylinder here become sharp i want it to look like a needle shape so press tab to go into edit mode press Alt G to switch to x-ray mode press 1 to switch to vertex select or you can press the button here and then select the vertices on the top of the cylinder then press S and press numpad 0 to scale it to the smallest size and then press enter and then now we want to move the origin point of this cylinder to the bottom currently is in the center i want it to be at the bottom so select the vertices at the bottom press shift s and select cursor to selected then press tab to exit the edit mode and go to object set origin and click origin to 3D cursor then press numpad 3 to see the right view and then we move up the cylinder to touch the Y-axis okay now we can start to apply material for four of this basic element but before this we need to set up the renderer and the environment light so we can see the material better go to render properties tab and change the render engine to cycles you can use Eevee as well if you want but i'm going to use cycles for this tutorial and then change the device to gpu and now we can change the viewport shading to display render preview ok now we can start to add material select the hexagon go to material properties tab and click new to add a new material then we split the screen and go to shader editor delete the principal node then press shift A and add a Emmision Shader connect it and then we want to change the color to orange you can put whatever color you want, you don’t have to follow exactly and then set the strength to 4 and now we want to copy this material to the cylinder so go to material properties tab and copy the material then select the cylinder and press new to add a new material and then paste the material then we can change this to white color and then we can select both of these and press ctrl j to join it together and then we can name it hexagon and next select the counter numbers go to material properties tab press new to add a new material and paste the material again and change the color to white color as well then we can name it counter numbers and then now select the cube and paste the material again and then we can change the color to a dark blue color and then we can change the strength to 2 then we can name it Earth Base and then select another Cube go to material properties tab delete remove this material add a new material again and paste the material then we can change the color to a light blue color then change the strength to 1 and you can play around with different color and strength later so just put it one for now and we can name this Earth Outline and then now we can move everything aside so we can start to add the globe but before this we need to move the cursor to the center again so to do this press shift s and select cursor to world origin okay now it's back to center and then we can start to add the globe press shift A and add a uv sphere change the radius to 2.6 go to geometry node editor and press new to apply a geometry node to the uv sphere and now we want to scatter the blue cube here onto the uv sphere so press shift A to add a point instant in the object column select Earth Base which is the dark blue cube then we can see the size of the cube is actually too big so to make it smaller press shift A and add a point scale then we can change the type to float and the Factor to .1 but we actually want to increase the dot and make the dot even smaller like the sample here so to do this we can add a subdivision surface node untick the boundary smooth change the level to 3 and in the point scale node change the factor to 0.005 to make it smaller and now.....we get the size we want then next we want to make the dots to form the world map shape so to do it in the geometry node editor press shift A and add a attribute texture sample then we can add it before the point scale and then press new to add a new texture then can name the texture Earth Base in the mapping column select uv map and in the result column type scale then click this button to jump to texture tab under the image section click open then we can select the image select the spec mask and open image i have include all these image in the description below so please download it and you can follow along and now we got the shape we want and maybe we can change the background color to black so we are able to see the material okay now we can go ahead to add the outline for the map so to do this select 3 of the node here and press shift D to duplicate it then move it below and then press shift A to add a join geometry node add in front of group output then connect it then press 2 to make a single user copy then we rename the texture to earth outline and then press this button to jump into texture tab under the image section again we need to press the 2 button to make a single user copy and then press the folder to load image and then select the outline image and open the image in the geometry node editors under the point instance change the instance object to Earth Outline then we can change the Point scale slightly bigger, so it’s look more obvious okay next we can start to add hexagon to the sphere okay to do this, press shift A again to add a point distribute node then press shift A again to add a point instant node connect it and under the point instant object column select Hexagon and we can see now the hexagon is too big so we want to make it smaller and after that we want to animate it to do it press shift A and add a Attribute sample Texture in the mapping column select uv map and type scale in the result column then click new to add a new texture then we can name the texture Hexagon and then click this button to jump into texture tab then change the texture tab to cloud under the color section... sorry for the watermark by the way.... activate the color ramp and then we drag the black color to around the center and you can see the hexagon is become smaller i think maybe we can decrease the amount of Hexagon a little bit so we can change it to 0.5 and now we can start to animate it so to do it, first make sure your time indicator is stay at zero and then go to the texture properties tab under the size section here change the size to 0.5 and then right click and insert keyframe then we drag the time indicator to the end of the frames (250) then change the size to 0.9 right click again and add a keyframe to be honest, i not sure why the key frame is not appear on the timeline if you guys know how to fix it please let me know in the comment below and if i find out how to fix it i will also update in my coming video too and next we can add the counter numbers go back to the geometry node editor duplicate the point instance in the object column select the counter numbers connect the point distribute to the point instance and then connect the point instant to the... joint geometry and now the counter numbers is too big and this is not what we want so to make it smaller with slightly different size we can add a attribute randomized node before the Point instance so press shift A and add a Attribute Randomize and then type scale at the attribute column then change the max value to 0.2 and seed to 7 and you don't have to follow me exactly you can play around with these value to get a different result and now we can see, all the counter numbers on the group is facing to the different direction and this is not what we want yet and we actually want it to facing into the same direction like the sample here so to do this press shift A and add Align rotation to vector node select X axis then change the vector value to.. x 0, y we put 90, and z we put 0 as well and now it's all faced to the same direction and we can set up our camera now so select the camera and press N to toggle the properties panel change the location to x X axis we put 19 y Y 0 and Z 0 as well then change the rotation to 90 0 90 then press numpad 0 to switch to camera view and then go to the camera properties tab and we want to set the focal length to 120 and now we want to add some depth of field to the scene we want to blur the background a little bit so....to do this we need to add a focus point to the camera press Numpad 7 to see the Top View press shift A to add an Empty Cube then we can name it focus point make it cover the area that we want to Focus press numpad 0 to back to camera view again select the camera go to camera properties tab and activate the depth of field and in the focus object column select the Focus Point then we can change the f-stop to 0.4 set the Blades to 6 that means our Bokeh will look like a hexagon shape you can see it here then i think we can make the text color darker a little bit i feel like it's too bright so select the counter numbers go to the material properties tab and change the strength to one yeah it looks better now and now i want to change the overall hexagon a little bit smaller too it's too big now so, select the Hexagon scale it slightly smaller and then press ctrl A to apply the scale press numpad 0 again to back to camera view and yeah it's look better now and next....we want to animate the counter numbers using animation node so to do this go to animation node press new to add a node tree and then Press Shift A and search for “Time info” press shift A again and search for animated float press shift a again and add a Float to text node and last we add a object output node then connect it and in the text object output node select the counter numbers and then press the little dot button beside the text to activate it and then go to animated float and we can start to set the start value and the End value for the counter numbers for the Counter Numbers here i want to remain the start value to 0, and we change the End value to 99 and the duration to 250 since my animation is end at 250 frame but of course if you have a longer animation, you can change the duration as well then go to the Float to text node and we can change the minimum length to 2 so..it will make the numbers shorter and next....we want to add a ring around the earth press numpad 7 to see the top view again press shift A to add a circle change the vertices to 32 and radius to 2.95 maybe we can make it bigger then press Tab to go into edit mode Press E and press S to Extrude scale it bigger and then press Tab again to exit edit mode go to Geometry node editor press new to apply a geometry node to the Ring press shift A to add a point distribute and then press shift A again to add a point instance node in the object column select the earth outline and then press shift A again to add a Attribute Randomize in the attribute column type scale then we change the maximum value to .006 make it very very small and then we change the seed 2 you can play around with these numbers as well don’t have to follow me exactly then go back to the Point Distribute node and increase the desity to 44 and change the seed to 2 as well and then press Numpad 0 to switch back to camera view and then now....i want to rotate the ring a little bit we can change the X-axis to 24 and Y-axis to -16 and finally we come to the last step we want to make some color correction to the Final render so...go to Render, and render the image and then...after finish the render......minimize it then go to the compositing tab and tick the use node then press Shift A and add a viewer node this node is allow me to preview the final outcome here and then we can go to the view tab and click Fit so..we can see the entire artwork and now we can start the color correction so...press Shift A, to add a Bright and contrast node and we change the bright value to 1 contrast to 4 and then press Shift A again to add a RGB curve and then we select the FilmLike Option and adjust it slightly brigther and then go to the red color tab and we adjust it slightly lower and then we done it so if you like my video please subscribe and see you next week Bye!!
