Basically, this works: glUniformMatrix4fv(glGetUniformLocation(self.shader.program, "projection"), 1, GL_FALSE, self.P) glUniformMatrix4fv(glGetUniformLocation(self.shader.program, "view"), 1, GL_FALSE, self.V) glUniformMatrix4fv(glGetUniformLocation(self.shader.program, "model"), 1, GL_FALSE, self.M) #version 330 core layout (location=0) in vec3 vertexPos; layout (location=1) in vec2 vertexTexCoord; layout (location=2) in vec3 vertexNormal; uniform mat4 model; uniform mat4 view; uniform mat4 projection; out vec2 fragmentTexCoord; void main(){ gl_Position = projection * view… Read More Is there a difference between GLSL/GLM and Python/numpy when it comes to 4×4 matrix multiplication?

My goal is to render a .pmx 3D model using PyOpenGL on pygame. I’ve found pymeshio module that extracts vertices and normal vectors and etc. found an example code on it’s github repo that renders on tkinter. I changed the code to render on pygame instead, didn’t change parts related to OpenGL rendering. The output… Read More problem with backface culling on OpenGL python

So i’m trying to make a function for displaying a circle, here’s the function : def drawCircle(x,y,size): glColor3f(1,1,1) glBegin(GL_TRIANGLE_STRIP) glVertex2f(0,0) glVertex2f(100,0) glVertex2f(100,100) glVertex2f(0,100) But when i try it, nothing display. If you have the solution, please explain me in detail, I’m not a profesional in opengl or in pyopengl. Here’s the code : import glfw… Read More No shape display pyopengl
