I am trying to make it work,
using both the hints that i've got here and those ones Mathias gave me.
Actually my code looks like:
// this is the 16 bit real image
LoadImg("3.raw",pixels);
Int16 data2[256*256*3];
RGBme(pixels,256,256,data2);
immagine[3]->set (Image::OSG_RGB_PF,256,256, 1, 1, 1, 0,(UInt8*) data2,
Image::OSG_UINT16_IMAGEDATA);
cubemap->setNegYImage(immagine[3]) ;
.
.
.
cubemap->setMinFilter(GL_LINEAR_MIPMAP_LINEAR);
cubemap->setMagFilter(GL_LINEAR);
cubemap->setWrapS(GL_CLAMP);
cubemap->setWrapT(GL_CLAMP);
cubemap->setEnvMode(GL_MODULATE);
cubemap->setExternalFormat(GL_RGB16);
i am getting no compilation errors,
but neither any output: my sphere is constantly black.
my fp should parse the real16 data all by himself. As for now
is it just a stupid:
TEMP texelcolor;
TEX texelcolor, inTexCoord, texture[0], CUBE;
MUL outColor, inColor, texelcolor;
so my idea is that the cube map is just an array of zeroes...
any clues?
