Web5.8.3 Oblique Projections OpenGL provides through glOrtho a limited class of parallel projections— namely, only those for which the projectors are orthogonal to the projection plane. As we saw earlier in this chapter, oblique parallel projections are useful in many ﬁelds.4 We could develop an oblique projection matrix directly; Web#version 330 core layout (location = 0) in vec3 aPos; uniform mat4 projection; uniform mat4 view; uniform mat4 model; void main() { gl_Position = projection * view * model * vec4(aPos, 1.0); } 所以這段代碼正在旋轉對象，但它們在旋轉時會變得非常扭曲，並且它們在屏幕的頂部和底部旋轉得更慢。 the bubbly bartender charlotte nc
