hi!
i was drawing an interleaved array with a single
texture, everything was fine and working, until
i got the idea of using multitexturing.
so i was defining two textures:
glActiveTextureARB(GL_TEXTURE0_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, id1);
glActiveTextureARB(GL_TEXTURE1_ARB);
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, id2);
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_ARB);
glTexEnvi(GL_TEXTURE_ENV, GL_RGB_SCALE_ARB, 2);
and rendered my terrain as before:
glInterleavedArrays( GL_T2F_N3F_V3F, 0, VertexArray );
glDrawArrays( GL_TRIANGLE_STRIP, 0, NumVertices );
of course, the desired effect didnt appear. i need to
call something like:
glMultiTexCoord2fARB(GL_TEXTURE0_ARB, 0.5, 1.0);
glMultiTexCoord2fARB(GL_TEXTURE1_ARB, 0.5, 1.0);
but calling this function would mean to go away from my
nice and fast vertex array, go back to working on every
vertex on its own …
or is there a way to use an interleaved-array together with
glMultiTexCoord2fARB ??
