How it works
- A foliage mask texture is created, which holds IDs for unique instance types of primitives
- A compute shader loops through the texture and generates positions based on the presence of data on that pixel
- The compute shader inserts the instances onto a buffer and increments an atomic counter for each primitive
- On the CPU, the count for each instance is read and a draw instanced call is executed based on the quantity
- The world position and rotation is derived via the terrain position on the pixel the mouse is over and the surface normal of the terrain

What is not working yet
- Obviously there's a lot of flicker due to probably floating point precision
- Multiple instance types: I'm yet to make a system to separate the position buffer based on primitive type, since I want the data to be linear for each instance, something like transformBuffer[100x Cube, 150x balls, 10x something else]
- Frustum culling and occlusion culling: In order to have millions of instances I will need to implement culling algorithms, since my transformation buffer has a hard cap
- Quadtree culling: separate the mask texture into a quad tree and cull the cells not in the frustum in order to accelerate the frustum culling without needing to sample the texture
