No glfwLoadTexture2D function?

[Harry Ayres]

Still going through tutorials (as time allows) and converting to Go as I... go. Came to glfwLoadTexture2D() and haven't found a go-gl version. I'm using the file opening method from the cube example, which is fine, but I was curious as to the reason for this function's absence.

Is it a stylistic choice, a lack of real need? Perhaps given the proliferation of image formats it's better to leave this out rather than have to pull in image format handlers from all over the place?

GLFW 3 does not have texture image loading support. See:

Cheers,

Stephen

Hi Harry,

To add to Stephen's answer, I suggest looking at a modern example that uses GLFW 3.1 to load and display a textured cube (if you haven't already seen this one):

https://github.com/go-gl/examples/tree/master/glfw31-gl41core-cube#cube

It demonstrates how you can load a texture using Go and upload it via gl.TexImage2D. Look at the newTexture func.

Otherwise, yeah, GLFW 3 removed that func with the rationale linked, which is as you guessed. Luckily, Go has support for many image format decoders in standard library (and others are supported via 3rd party libraries):

Hope that helps!
