- Performance improvements:
— Modified GLIM to perform a pre-pass + reserve mem when gathering vertex data (position + attributes) before uploading it to the GPU. Attributes and positions are added to a 4byte per element vector then uploaded in bulk using insert that does a lot of memory allocations in the background. The pre-pass reserves memory up-front
— Changed the animation data upload from a double-buffered approach to a single-buffer 3x data size round-robin mechanism. This required several changes to UBO/SSBOs:
-— Padding is added on bind/create/update etc to align ranges with the UBO alignment returned by OpenGL
-— All ranges are now expressed in number of primitives instead of number of bytes to simplify the public interface
- Removed an old debug prinfn callback
- Fixed a bug when only one single node is visible (offset != range check on UBOs was wrong)
- ShaderBuffer info in RenderPackage now takes an offset and a range to bind the buffer (instead of just the location)
