UUSL Textures

List of functions:

The Unified UNIGINE shader language (UUSL) unifies the way of using textures in shaders. You need to define the texture slot in the material, initialize the texture in the shader's code and then use it.

Here is an example of using texture in the fragment shader's code:

UUSL

// Include the UUSL header file
#include <core/shaders/common/fragment.h>

// Initialize a textures.
// You don't need to define texture slot
// by using define directive
INIT_TEXTURE(0,TEX_DEPTH)
INIT_TEXTURE(1,TEX_NORMAL)
INIT_TEXTURE(2,TEX_ALBEDO)
INIT_TEXTURE(3,TEX_SHADING)

/* Input and output structures */

MAIN_BEGIN(FRAGMENT_OUT,FRAGMENT_IN)

	/* some code */

	GBuffer gbuffer = GBufferDefault();
	
	loadGBufferAlbedo(gbuffer, TEXTURE_OUT(TEX_ALBEDO),uv);
	loadGBufferShading(gbuffer, TEXTURE_OUT(TEX_SHADING),uv);
	loadGBufferNormal(gbuffer, TEXTURE_OUT(TEX_NORMAL),uv);

	/* some code */
MAIN_END

Warning

You should add a new line (press Enter) after closing the instruction.
