How do I use 3D textures in C++ graphics programming?

To use 3D textures in C++, you'll typically use a graphics API like OpenGL or DirectX. Do you have a specific API in mind?

I'm using OpenGL. What are the steps to load a 3D texture?

First, you'll need to load your texture data, then generate a texture ID, bind it, and set the texture parameters. Finally, upload the texture data using glTexImage3D.

Can you provide a code snippet for that?

Sure! Here's a basic example:

GLuint textureID;
glGenTextures(1, &textureID);
glBindTexture(GL_TEXTURE_3D, textureID);
// Set texture parameters
// Load your texture data
// glTexImage3D(...);

What about texture filtering and wrapping options?

You can set filtering options using glTexParameteri for GL_TEXTURE_MIN_FILTER and GL_TEXTURE_MAG_FILTER, and wrapping options with GL_TEXTURE_WRAP_S, GL_TEXTURE_WRAP_T, and GL_TEXTURE_WRAP_R.
