Drawing Problem + Picture

OpenGL OpenGL: Basic Coding

hi

I have always the same problem… i can see thought the montains of my height map … but now it’s changed because before it was only by looking in direction of the origin (0,0) and now it’s when i’m looking at the opposite :-/ i don’t know what have done that made this :frowning:
(Screenshot at the end)

glEnable(GL_DEPTH_TEST) was already actived…

My Init Code:

glClearDepth(1.0f);
glDepthFunc(GL_LEQUAL);
glEnable(GL_DEPTH_TEST);
Set_Camera(45.0f,640.0f,480.0f,3000.0f);
glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);
glHint(GL_POINT_SMOOTH_HINT, GL_NICEST);
glHint(GL_POLYGON_SMOOTH_HINT, GL_NICEST);

Problem Resolve :smiley:
Lucky i am today lol :slight_smile:

Just for the fun i’ve changed something to see what it is and that resolved my proble !

The Problem was :
gluPerspective(angle_of_vision,(GLfloat)largeur/(GLfloat)hauteur,0.1f,distance);

I’ve replace 0.1f by 1.0f and that worked :-).
