Functions

computeTextureDataSize

fun computeTextureDataSize(format: Texture.Format, type: Texture.Type, stride: Int, height: Int, alignment: Int): Int

Computes the required buffer size for pixel data given format, type, stride, and alignment parameters.

getMaxArrayTextureLayers

fun getMaxArrayTextureLayers(engine: Engine): Int

Returns the maximum number of layers supported by texture arrays. Guarantees at least 256.

getMaxTextureSize

fun getMaxTextureSize(engine: Engine, type: Texture.Sampler): Int

Returns the maximum size in texels of a texture of the given type. Guarantees at least 2048 for 2D textures, 256 for 3D textures.

isProtectedTexturesSupported

fun isProtectedTexturesSupported(engine: Engine): Boolean

Returns whether this backend supports protected textures.

isTextureFormatCompressed

fun isTextureFormatCompressed(format: Texture.InternalFormat): Boolean

Returns whether a particular format is compressed.

isTextureFormatMipmappable

fun isTextureFormatMipmappable(engine: Engine, format: Texture.InternalFormat): Boolean

Queries whether a backend supports mipmapping of a particular format.

isTextureFormatSupported

fun isTextureFormatSupported(engine: Engine, format: Texture.InternalFormat): Boolean

Queries whether a backend supports a particular format.

isTextureSwizzleSupported

fun isTextureSwizzleSupported(engine: Engine): Boolean

Queries whether the backend supports texture swizzling.

validatePixelFormatAndType

fun validatePixelFormatAndType(internalFormat: Texture.InternalFormat, pixelDataFormat: Texture.Format, pixelDataType: Texture.Type): Boolean

Validates whether a combination of internal format, pixel format, and pixel data type is valid.
