It's much better explained in this short youtube video
Note that my light is not going somewhere and coming back; it is always located half way between the camera and the cube.
This is my function for drawing the floor tiles:
void drawFloor(){
float size = 20.0;
float startX = -60.0f;
float startZ = 60.0f;
glDisable(GL_COLOR_MATERIAL);
glPushMatrix();
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, _textureId);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
for(int x = 0;x < 6; x++){
for(int z = 0;z < 6; z++){
glBegin(GL_QUADS);
glNormal3f(0.0f, 1.0f, 0.0f);
glTexCoord2f(0.0f, 0.0f);
glVertex3f(startX + size*x, 0.0f, startZ + -size*z);//bottom-left
glTexCoord2f(1.0f, 0.0f);
glVertex3f(startX + size + size*x, 0.0f, startZ + -size*z);//bottom-right
glTexCoord2f(1.0f, 1.0f);
glVertex3f(startX + size + size*x, 0.0f, startZ + -size + -size*z);//top-right
glTexCoord2f(0.0f, 1.0f);
glVertex3f(startX + size*x, 0.0f, startZ + -size + -size*z);//top-left
glEnd();
}
}
glDisable(GL_TEXTURE_2D);
glPopMatrix();
glEnable(GL_COLOR_MATERIAL);
}
Question: How can i make my light not jump and light the tiles smoothly?
