The GPUPlantPainter is a plant painting tool that allows you to paint vegetation on any mesh renderer easily. Unlike Unity or other terrain packages, which can only paint on their own surfaces. In addition, the GPUPlantPainter offers GPU per-instance culling and instanced rendering, avoiding the use of SSBO (Shader Storage Buffer Object), significantly improving cross-platform compatibility (Mali vertex shader does not support SSBO).
Furthermore, it utilizes a weight map and template transform architecture, greatly reducing the memory usage of the transform buffer and meeting the goal of rapid loading.
