## Calculate Normals Geometry Shader

问题 Im currently writing my own GLSL shaders, and wanted to have smooth shading. The shading worked when i calculated the normals bevore sending them to a VBO, but the problem here is when I implement animations with bone matricies, the normals are not corect. I am using a geometry shader to calculate the normals, but i cant find out how to smooth them. Here is my geometry shader: #version 150 layout(triangles) in; layout (triangle_strip, max_vertices=3) out; in vec2 texCoord0[3]; in vec3
