   Render model in non perspective mode
  this might be simple but how do i setup a non perspective viewingwhere i can draw a 3d model but without the perspectivelike in blender where you choose Orthographici tried to draw the x,y (z = depth) coordinates of my model in 2d view but didnt succeedis this the correct way or am i wrong?thanks   
  Is this software rendering of some sort, or are you using a graphics API?   ;  sry forgotits opengl   ;  OpenGL has functions for orthographic projection; just google or check out the Red Book.   ;  iknowglOrtho(left,right,top,bottom,znear,zfar)gluOrtho2D(left,right,top,bottom)but is that enoughshall i useglVertex2d  to diaply my 3d model?will lightning work?   ;Quote:Original post by Hunter_ExglOrtho(left,right,top,bottom,znear,zfar)gluOrtho2D(left,right,top,bottom)but is that enoughshall i useglVertex2d  to diaply my 3d model?will lightning work?Notice please that projection is a mapping from a 3 dimensional space to a 2 dimensional space (in the case of 3D gfx; mathematically it is a general mapping from a space to a space of less dimensions). So in both cases you use glVertex3/glNormal3 routines to supply the 3D geometric scene data to GL as usual. (glVertex2 routines are more common for UI elements and such, since it implies a depth of 0.)Notice furthur that gluOrtho2D may be not exactly what you are looking for since it restricts the depth range in a fixed way. Stay with glOrtho in general.[Edited by - haegarr on April 20, 2006 1:32:57 PM]
