If( dot((c_vCorner000.xyz+c_vCorner110.xyz)*c_vInverseProjection.The kit includes a ready-made scene that you can use in your game, movie or render for advertising or promotional materials. So I added an offset and 'made the frustum larger'. Using this test on the center would cause voxels to disappear to early. These are different: in DirectX and in OpenGL. The z coordinate equation depends on which clipping planes are used. Multiplying this with gives the simple equations: The homogeneous coordinate must be inside the unit volume. In projection space frustum culling is easy. To avoid two vector-matrix transformations the vectors must be added in object space (before transformation) or in projection space (after transformation of the center). One could compute some offset vectors to a voxel center in the shader, but since these vectors are equal for all instances they can also be precomputed. Spanning the cubeįor a single voxel based model all cubes have the same size and rotation. Therefore my shader emits at most 12 vertices for 3 quads.

It happens that backface culling for a cube will always remove one of two opposite faces. On the other hand we can decide if a cube is visible before any triangle is created. Both are possible but effectively to large to be efficient. Why not whole cubes? Depending on the vertex normals (smoothed or per face) this requires either 16 or 24 vertices. It is common practice to create billboards in form of quads inside a geometry shader. This is what I did and I will explain it in detail. Indeed I had a reference implementation for many instanced cubes but I wanted to test if this can be outperformed.

To update a local change only the instance information must be overwritten or masked and bus-traffic should be low. Since there is no need to store real vertices (only one real cube mesh and many instance information) this would be efficient. The advantage is that only a few data per cube is required on GPU. It is possible, but not probable, that I benchmark that later. I assume this to be fastest anyway but it requires plenty of space. Updating the information is somewhat tricky because we need to know a neighborhood. Drawing static meshes is just the fastest thing a GPU can do. One could create quads for each surface side of a cube. This approach would probably not be realtime. All models in the game have there own dynamic transformation, hence there would be many relatively small 3D textures and I have to test which objects are hit by a ray before using a sparse octree traversal. It is possible to use octrees - which are the natural representation of voxel hierarchies - to efficiently ray-cast a 3D texture.

Following Ideas can suffice for this task: They allow much more dynamical updates because not every change causes a recomputation of complex meshes. There are people how don't like that and yes there are algorithms as marching cubes to create continuous surfaces but I considered real cubes as the way to go. Which approaches do exist?įirst of all I decided that I want to render voxels directly in the form of boxes. Even if we store only one byte for each this requires 962081 PB RAM or disc space. To store the earth in 1 m³ large volume elements we would need 10^21 of them. Therefore spaceships and planets and solar systems and. What is many? Well Monolith is a space strategy game based on voxels. The nice things with them is that the logical arrangement in a 3D textures allows simple algorithms, e.g. What is a Voxel? A voxel is a small volumetric element - it is a pixel in 3D. As it happens I try to render many voxels in my latest project Monolith (Project page is still pending, but you can look on github for it).
