With the development of mobile platforms, mobile phones have gradually entered the era of Opengl3.0, and a new technology has entered our field of vision: Gpu Instancing. This technology has a qualitative improvement for large-scale object rendering.
By default, skeletal animation can't use this technique, but we can save the matrix information of the skeletal animation into a texture and finish the skin in the shader to meet the usage conditions of Gpu Instancing and achieve a significant performance improvement.
