GLFrameBuffer & GLTexture

[RuffledPlume]

Aims to reduce boilerplate and simplify the process of working with glFrameBuffer & glTexture.

Example declarations:

sceneFBO = new GLFrameBuffer(new GLFrameBufferDesc()
					.setWidth(canvas.getWidth())
					.setHeight(canvas.getHeight())
					.setMSAASamples(msaaSamples)
					.setColorAttachment(GLAttachmentSlot.COLOR0, backbufferFormat, GLTextureParams.DEFAULT())
					.setDepthAttachment(GLTextureFormat.DEPTH32F, GLTextureParams.DEFAULT()));

shadowMapFBO = new GLFrameBuffer(
					new GLFrameBufferDesc()
						.setWidth(shadowFBOSize)
						.setHeight(shadowFBOSize)
						.setDepthAttachment(GLTextureFormat.DEPTH32F,
							new GLTextureParams()
								.setSampler(GLSamplerMode.NEAREST_CLAMP)
								.setTextureUnit(TEXTURE_UNIT_SHADOW_MAP)
								.setBorderColor(new float[] { 1.0f, 1.0f, 1.0f, 1.0f})));

tileHeightMapTex = new GLTexture(EXTENDED_SCENE_SIZE, EXTENDED_SCENE_SIZE, MAX_Z, GLTextureFormat.R16I, new GLTextureParams()
					.setType(GLTextureType.TEXTURE3D)
					.setSampler(GLSamplerMode.NEAREST_CLAMP)
					.setTextureUnit(TEXTURE_UNIT_TILE_HEIGHT_MAP));

int anisotropySamples = config.anisotropicFilteringLevel();
texMaterialTextureArray = new GLTexture(textureSize, textureSize, textureLayers.size(), GLTextureFormat.SRGB8_ALPHA8,
				GLTextureParams.DEFAULT()
					.setType(GLTextureType.TEXTURE2D_ARRAY)
					.setTextureUnit(TEXTURE_UNIT_GAME)
					.setGenerateMipmaps(anisotropySamples > 0)
					.setAnisotropySamples(anisotropySamples)
					.setImmutable(true)
					.setDebugName("Material Textures Array"));
