Hi,
I try to create a cubeMap on a sphere. It works but all my images (.bmp) on
cubemap's faces are flip ...
In addition, with .dds files I have this error for each file :
notify(WARN)<<"Texture::getCompressedSize(...) : cannot compute correct size of
compressed format ("<<internalFormat<<") returning 0."<<std::endl;
I compress my bmp's files with nvdxt command tool line. My options are :
nvdxt -dxt1 -quality_highest -rgb -file back.bmp for example
But in Texture::getCompressedSize() , the internal GLenum internalFormat must
be :
Code:
if (internalFormat == GL_COMPRESSED_RGB_S3TC_DXT1_EXT || internalFormat ==
GL_COMPRESSED_RGBA_S3TC_DXT1_EXT)
blockSize = 8;
else if (internalFormat == GL_COMPRESSED_RGBA_S3TC_DXT3_EXT || internalFormat
== GL_COMPRESSED_RGBA_S3TC_DXT5_EXT)
blockSize = 16;
And, last question : someone has succeed to load one file .dds which contains
the cubemap ???
I hope you should help me !
Thank you!
Cheers,
Kévin
