I’d like to learn use OpenGL. I’d like my first project to render and manipulate a model I’ve built with Blender in my C++ application.
This OpenGL tutorial looks promising, Blender is mentioned in some lessons I’ve gone through. Any other Blender oriented OpenGL tutorials I should look at?
The lesson I’m hung up on right now deals with applying textures. It concludes with a recommendation to use Compressonator.
A search for “Compressonator” suggests that is a valid topic for this forum so here goes…
I’m running Compressonator version 2.4.3213.0.
On this page, about 3/4 down, the tutorial suggests this method to select compression to DXT1, DXT3 or DXT5:
Ok, got it. So I fire up Compressonator but I don’t see anything offering up a choice of DXT formats. I’ve selected a BMP file and clicked buttons all over Compressonator’s window.
When I try to run the “Getting Started” exercise from Compressonator’s help I was unable to bring up the Compressonator menu I saw in the tutorial:
Where the text above the Compressonator screenshot in the tutorial tells me to “Generate mipmaps”, all I can get to is that little “Generate MIP Maps” window asking me to select a “Lowest Mip-level”. How do I see the selection of texture formats in the tutorial’s screenshot?
Thought you should know, DXT is a directX format. Not openGL.[/QUOTE]
Thanks Paul:
That tutorial looks good, the model section mentions Blender.
I’d like to pursue this course for a little bit.
I won’t pretend to understand how this is supposed to work. It looks like a BMP file is fed to Compressonator, which uses the DXT format in the compression, but then exports a DDS file for consumption by the OpenGL code.
Is Compressonator a commonly used tool for working with textures?
I’m curious why Compressonator isn’t providing the menus I see in the tutorial’s Compressonator screen shots.
