Hi,

I tried to fix the zfight on ATI cards.. with a "glPolygonOffset(-1.0, -1.0);".
Since I it seems to never zfight on my nvidia card, i put here a news binary here :

Get the new exe (patch) here

If you use ATI card, could u tell me if that fix the problem plz, many thanks!
The renderer seems to be faster with glDephMask off, and an useless texture binding removed.

Here is the new lightamaping fonction :


void shader_Lightmap(pFace pCurr)
{
int line;
int col;
int i;

if(!pCurr)
return;

glEnable(GL_BLEND);
glBlendFunc(GL_ZERO,GL_SRC_COLOR);
glEnable(GL_TEXTURE_2D);
glEnable(GL_DEPTH_TEST);

gl_BindTexture((int)(txid_LIGHTMAP_N[ + (pCurr->LightID*ONEOVER256)));
line = (int)((pCurr->LightID%256) * ONEOVER16);
col = (pCurr->LightID%256) % 16;

glDepthFunc(GL_LEQUAL);
glDepthMask(GL_FALSE);
glEnable(GL_POLYGON_OFFSET_FILL);
glPolygonOffset(-1.0, -1.0);

glBegin(GL_TRIANGLES);
for(i=0 ; i<3 ; i++)
{ glTexCoord2f((pCurr->Vertice.U_lm+col)*ONEOVER16,(pCurr->Vertice.V_lm+line)*ONEOVER16);<br>glVertex3f(pCurr->Vertice.X,pCurr->Vertice.Y,pCurr->Vertice.Z);<br>}<br>glEnd();<br><br>glDisable(GL_POLYGON_OFFSET_FILL);<br>glDepthMask(GL_TRUE);<br>glDepthFunc(GL_LESS);<br><br>glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);<br>glDisable(GL_BLEND);<br>}<br> </i> <br><br><SPAN CLASS=editedby>[edited by - sunhp2 on January 8, 2004 3:49:33 PM]</SPAN>
