Hello,

i'm trying to draw stencil shadows with PSPGL but i can't get it working,

here is the code:

Code:

   glPushAttrib(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_ENABLE_BIT |
      GL_POLYGON_BIT   | GL_STENCIL_BUFFER_BIT   );

   glDisable(GL_LIGHTING);
   glDisable(GL_FOG);
   glDepthMask(GL_FALSE);
   glDepthFunc(GL_LEQUAL);
   glEnable(GL_STENCIL_TEST);
   glColorMask(GL_FALSE, GL_FALSE,   GL_FALSE, GL_FALSE ); // no color buffer drawing
   glStencilFunc(GL_ALWAYS, 1,   0xFFFFFFFFL   );
   glColorMask(0, 0, 0, 0);
   glEnable(GL_CULL_FACE);

      glStencilOp(GL_KEEP, GL_INCR, GL_KEEP);
      glCullFace(GL_FRONT);

      glBegin(GL_TRIANGLES);

      s32 i;
      for(i=0; i<count; ++i)
         glVertex3f(triangles[i].X, triangles[i].Y, triangles[i].Z);

      glEnd();

      glStencilOp(GL_KEEP, GL_DECR, GL_KEEP);
      glCullFace(GL_BACK);

      glBegin(GL_TRIANGLES);

      for(i=0; i<count; ++i)
         glVertex3f(triangles[i].X, triangles[i].Y, triangles[i].Z);

      glEnd();


   glPopAttrib();
