How do you make a cubemap?
Select Assets > Create > Legacy > Cubemap from the menu, and drag six textures into empty slots in the inspector. Textures for the corresponding cubemap face. Width and Height of each Cubemap face in pixels. The textures will be scaled automatically to fit this size.
What are SSR reflections?
Screen Space Reflections or SSR is a camera effect that adds local reflections to a reflective surface. This effect can add further realism to a model making them more true to life. This affect can be enabled on the Default Camera or any Camera Entity in a 3D Document.
How do you make a cubemap in blender?
Rendering a cubemap/skybox
- Create a Cube around your scene.
- Mark seams to match a cubemap. (
- Flip normals to the inside. (
- UV unwrap the cube. (
- Create a cube material, enable shadeless to prevent shading and specularity of the cube.
- Check all your lights and stuff like that.
- Save the image and use it as cubemap.
What is SSAO in gaming?
Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time. It was developed by Vladimir Kajalin while working at Crytek and was used for the first time in 2007 by the video game Crysis, also developed by Crytek.
How does screen space reflections work?
Screen Space Reflection is calculated by ray-marching from reflection points on the depth map to other surfaces. A reflection vector is calculated for each reflective point in the depth buffer. This vector is marched in steps until an intersection is found with another point on the depth buffer.
How to draw a sphere in OpenGL?
In order to draw the surface of a sphere in OpenGL, you must triangulate adjacent vertices to form polygons. It is possible to use a single triangle strip to render the whole sphere. However, if the shared vertices have different normals or texture coordinates, then a single triangle strip cannot be used.

How to create a texture map of an icosphere?
The subdivision algorithm is splitting the 3 edge lines of each triangle in half, then extruding the new middle point outward, so its length (the distance from the center) is the same as sphere’s radius. In order to generate a texture map of an icosphere, you need to unwrap the 3D geometry on a plane (paper model).
