3D using light and texture together

[dheart88]

Is it possible to use light and texture together? I can't see the differences of light implementation...

[elhobbs]

Yes it is possible. Make sure you not setting the vertex color after you send the required normal commands as this will override the color calculated by the normal command. Also, did you set the ambient, diffuse, and specular color materials?

will it work if i use calllist? all my objects are exported from 3dsmax (3ds format into bin)

[elhobbs]

yes, though the same issues apply.

[dheart88]

can you pls give me some example? It didn't work in my place... is it because I use RGB16 instead of RGBA?

[elhobbs]

this is the code I use:

per frame I call:

Code: Select all

        glLight(0, RGB15(31,31,31) , floattov10(r_vright[0]), floattov10(r_vright[1]), floattov10(r_vright[2])); 

per object that will use lighting I turn on the light and set the colors

Code: Select all

glPolyFmt(POLY_ALPHA(31) | POLY_CULL_FRONT | POLY_ID(6) | POLY_FORMAT_LIGHT0 | (1 << 13)); 
glColor3b(shadelight,shadelight,shadelight);
glMaterialf(GL_AMBIENT, RGB8(ambientlight,ambientlight,ambientlight)); 
glMaterialf(GL_DIFFUSE, RGB8(shadelight,shadelight,shadelight)); 
glMaterialf(GL_SPECULAR, RGB8(shadelight,shadelight,shadelight)); 
 

then for each point of each triangle I send the normal, the texcoord, and then the vertex - in that order.

Thx for your help.
