问题 I am using #include <gl/freeglut.h> but getting " fatal error: GLUT/freeglut.h file not found " ** I tried reinstall "brew install glew freeglut" and also " #ifdef __APPLE__ #include <OpenGL/gl.h> #include <GLUT/glut.h> #else #include <GL/gl.h> #include <GL/glut.h> #endif" I also tried: #include <GL/freeglut.h> but none of them worked... 来源： https://stackoverflow.com/questions/65655868/fatal-error-glut-freeglut-h-file-not-found-catalina

问题 I'm trying to implement a ray caster and I'm starting out with simple .obj files (utah-teapot) and currently I only made classes for Spheres and Triangles, I basically have all the functions for the intersections, generating view rays, etc.. all ready but I just can't seem to be able to parse the .obj file into triangles (three vectors each) so I can have the ray casting possible on custom .obj files instead of just spheres. This is my current .obj file parser (didn't include the full working

问题 I tried to read obj file with pyopengl but error come from glGenList(1) I just want to read the file and display in opengl Pls can you help me with full code; Am tired of stack and error it took me 3hrd to post this from OpenGL.GL import * from tkinter import messagebox import sys filename = input('pls input file path: ') class OBJ: def __init__(self, filename, swapyz=False): """Loads a Wavefront OBJ file. """ self.vertices = [] self.normals = [] self.texcoords = [] self.faces = [] material =

问题 I've just discovered FLTK and I made a makefile for my test. Here is my makefile: ################ template makefile ############## # We don't know what compiler to use to build fltk on this machine - but fltk-config does... CC = $(shell fltk-config --cc) CXX = $(shell fltk-config --cxx) # Set the flags for compiler: fltk-config knows the basic settings, then we can add our own... CFLAGS = $(shell fltk-config --cflags) CXXFLAGS = $(shell fltk-config --cxxflags) -I/System/Library/Frameworks

问题 I was making a shader with GLSL so I could apply texture arrays to a cube when I ran into an issue. The issue was that layout wasn't supported in the version I was using. Easy fix, use a later version, but the problem with that was that I don't have support for later versions that support layout . I was wondering, is it possible to get support for later versions of GLSL, and if so, how would I do such a thing? This is my current GLSL code for applying textures Vertex Shader: #version 130

问题 I'm trying to print the bitmap data to the screen with opentk. GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgba, data.Width, data.Height, 0, OpenTK.Graphics.OpenGL.PixelFormat.Bgra, PixelType.UnsignedByte, data.Scan0); I get an error on the part. My guess is I'm writing the formats wrong. With Format8bppIndexed, I can view properly in picturebox. My incoming image is black and white. incoming data; BitmapSingleImage = new Bitmap(rsSplitWidth, rsSplitHeight, rsSplitWidth,

问题 I'm developing a version of the Frogger game for a University project, and we got to the light and materials part. The problem I have is: when I set the materials for the frog, it applies them to all other objects that are drawn. How do I make it so that it only applies to the frog? If I disable GL_COLOR_MATERIAL after the draw or after the material properties have been set, everything becomes red. void Frog::draw(void) { Vector3 _pos = Entity::getPosition(); glPushMatrix(); glEnable(GL_COLOR
