Thread: BMP Loading Questions, More OpenGL!!! :D

Code:

int LoadGLTextures()									// Load Bitmaps And Convert To Textures
{
	int Status=FALSE;									// Status Indicator

	AUX_RGBImageRec *TextureImage[2];					// Create Storage Space For The Texture

	memset(TextureImage,0,sizeof(void *)*1);           	// Set The Pointer To NULL

	// Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit
	if (TextureImage[0]=LoadBMP("Data/NeHe.bmp"))
	{

		Status=TRUE;									// Set The Status To TRUE

		glGenTextures(1, &texture[0]);					// Create The Texture

		// Typical Texture Generation Using Data From The Bitmap
		glBindTexture(GL_TEXTURE_2D, texture[0]);
		glTexImage2D(GL_TEXTURE_2D, 0, 3, TextureImage[0]->sizeX, TextureImage[0]->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[0]->data);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
	}


	if (TextureImage[0])									// If Texture Exists
	{
		if (TextureImage[0]->data)							// If Texture Image Exists
		{
			free(TextureImage[0]->data);					// Free The Texture Image Memory
		}

		free(TextureImage[0]);								// Free The Image Structure
	}

	// Load The Bitmap, Check For Errors, If Bitmap's Not Found Quit
	if (TextureImage[1]=LoadBMP("Data/NeHe1.bmp"))
	{

		Status=TRUE;									// Set The Status To TRUE

		glGenTextures(1, &texture[1]);					// Create The Texture

		// Typical Texture Generation Using Data From The Bitmap
		glBindTexture(GL_TEXTURE_2D, texture[1]);
		glTexImage2D(GL_TEXTURE_2D, 0, 3, TextureImage[1]->sizeX, TextureImage[1]->sizeY, 0, GL_RGB, GL_UNSIGNED_BYTE, TextureImage[1]->data);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
		glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
	}


	if (TextureImage[1])									// If Texture Exists
	{
		if (TextureImage[1]->data)							// If Texture Image Exists
		{
			free(TextureImage[1]->data);					// Free The Texture Image Memory
		}

		free(TextureImage[1]);								// Free The Image Structure
	}

	return Status;										// Return The Status
}

Now you see, this code is cool and all, and it loads my textures, but........ Why would I need to modify the glGenTextures() function to generate more than 1 texture at a time....

Do I need to do this to allocate memory for each time I use this texture? Say 3 sides of my cube are one texture, and the other 3 are some other texture, do I need to generate 3 textures (for better memory allocation) Or is it save generating one texture for unlimited usage of the texture....
