now shaders ask the device to create a buffer, if a buffer of the same name and size already exist then a pointer to that buffer is returned instead. Going to see if something similar can be added to the opengl end.
opengl can now compile with ubo buffer objects similar to cbuffers on dx side.
cleaned double up of data from both sides, gfxhandles only need to use the desc info instead of holding onto its own.
Reverted back to a 2d array since when the const buffer changes are made to the shaders they will be completely swapped out for a 1d array with a max size of 16 for the program, id3d11buffers will be shared across shaders apart from object buffers. We still need to decide on a structure to get everything setup so to keep functionality a max of 2 buffers per stage with 1 buffer as a padding so we can start coding constant buffers right away
need to reverse the bitshift on shaderstages so we get values between 0-5, need to also revert the mBoundConstVec back to a 2dimensional array so that the binding point can be dynamic as well.
Added multiple descriptions to handles.
While maps are very efficient and match data very quickly due to hashing and what not, they are tricky memory wise, we cant clear them if they are only made up of structs and enums. Need to explore other methods for doing this. Original system had a sub buffer system with a check based on whether the handle was marked vertex/pixel. With 6 stages possible now we need to think of a more effective method. Since shaderstage is now a bit flag maybe some sort of streaming setup could be used to write without a loop.
working example, renders all gui controls.
We still cant render a scene, something to do with the constant buffer at slot 0 of the vertex shader being too small..... gotta figure this one out..................
Refactored DX Shader compilation and reflection to be more similar to opengl
Added support for more than 1 const buffer per shader stage.
This is boilerplate code, no functionality yet, that will be added in further commits. Though this builds without errors do not try and run it at this point.
- Supports GL, D3D9 & D3D11
- Extends vertex formats & shadergen to support blend indices and weights
- Adds basic support for using 4x3 matrices for shader constants
- Supports software fallback
