load ktx file about ktx-software HOT 1 CLOSED

I am not entirely sure what you are asking.

To load a ktx file and get id of the texture that was created use one of the ktxLoadTexture[FMN] functions, e.g.

GLint texName = 0;
GLenum target;
GLboolean isMipmapped;
GLenum glerror;
GLubyte* pKvData;
GLuint  kvDataLen;
KTX_dimensions dimensions;
KTX_error_code ktxerror;

filename = "myfile.ktx";

ktxerror = ktxLoadTextureN(filename, &texName, &target,
                           &dimensions, &isMipmapped, &glerror,
                           &kvDataLen, &pKvData);

The texture name (id) is returned in the texName variable.

Alternatively you can generate the texture name yourself and assign it to texName. That name will be used for the texture created by ktxLoadTexture*.
