hi. glfw changelog 3.0 says “Removed the entire image loading API”

what is its replacement?

what is glfwLoadTexture2d’s replacement?

Good project! Keep on! Thanks everyone.

EDIT:No replacement.I have to use gl funtions?

There is no replacement, see the notes on texture loading.

There are a few alternatives out there, for example SOIL2

Thank you for quick reply. i think i can do it by

glteximage2d(). So i should look at streams(in c++) a bit.

Whats the best way passing texture image to opengl3+?

is it stream or array?

REGARDS.

You should note that OpenGL requires images loaded via the data pointer to glTexImage2D to be in a different format to most disk image formats. Uncompressed formats like TGA, PPM, PGM and PBM can be fairly simple to write loaders for, but you’ll still need to parse and remove the header.

Since GLFW is permissively licensed, a good approach might be to take a look at the 2.0 image loader code and modify this (keeping the license header etc.). However a simple loader library like SOIL2 will give you wider format support plus support for compressed DXT formats and mipmap generation.

i have looked at SOIL2 yet.i like it.i have not to deal glteximage2d stuff;)

i maybe look at it only just to learn background of.

thanks again.
