Can someone please help me find out why the texture is flickering? HERE IS MY CODE:
#include <OpenGLSB.h>
#include <GLTools.h>
#include “glbmp.h”

glEnable(GL_TEXTURE_3D);
}
void RenderScene(void)
{
GLuint texture = 0;
glbmp_t bitmap;
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
glbmp_LoadBitmap(“grass.bmp”, 1, &bitmap);
//generate and bind the OpenGL texture
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
//copy data from bitmap into texture
glTexImage2D(GL_TEXTURE_2D, 0, 3, bitmap.width, bitmap.height,0, GL_RGB, GL_UNSIGNED_BYTE, bitmap.rgb_data);
