Typedef Documentation

typedef simd::VecType<float, OIIO_TEXTURE_SIMD_BATCH_WIDTH>::type Tex::FloatWide

A type alias for a SIMD vector of floats with the batch width.

Definition at line 141 of file texture.h.

typedef simd::VecType<int, OIIO_TEXTURE_SIMD_BATCH_WIDTH>::type Tex::IntWide

A type alias for a SIMD vector of ints with the batch width.

Definition at line 144 of file texture.h.

typedef uint64_t Tex::RunMask

RunMask is defined to be an integer large enough to hold at least BatchWidth bits. The least significant bit corresponds to the first (i.e., [0]) position of all batch arrays. For each position i in the batch, the bit identified by (1 << i) controls whether that position will be computed.

Enumeration Type Documentation

enum Tex::InterpMode

strong

Interp mode determines how we sample within a mipmap level

Enumerator
Closest	Force closest texel.
Bilinear	Force bilinear lookup within a mip level.
Bicubic	Force cubic lookup within a mip level.
SmartBicubic	Bicubic when magnifying, else bilinear.

Definition at line 120 of file texture.h.

enum Tex::MipMode

strong

Mip mode determines if/how we use mipmaps

Enumerator
Default	Default high-quality lookup.
NoMIP	Just use highest-res image, no MIP mapping.
OneLevel	Use just one mipmap level.
Trilinear	Use two MIPmap levels (trilinear)
Aniso	Use two MIPmap levels w/ anisotropic.
StochasticTrilinear	DEPRECATED Stochastic trilinear.
StochasticAniso	DEPRECATED Stochastic anisotropic.

Definition at line 108 of file texture.h.

enum Tex::Wrap

strong

Wrap mode describes what happens when texture coordinates describe a value outside the usual [0,1] range where a texture is defined.

Enumerator
Default	Use the default found in the file.
Black	Black outside [0..1].
Clamp	Clamp to [0..1].
Periodic	Periodic mod 1.
Mirror	Mirror the image.
PeriodicPow2	Periodic, but only for powers of 2!!!
PeriodicSharedBorder	Periodic with shared border (env)
Last	Mark the end – don't use this!

OIIO_API Wrap Tex::decode_wrapmode

(

const char *

)

Utility: Return the Wrap enum corresponding to a wrap name: "default", "black", "clamp", "periodic", "mirror".

OIIO_API Wrap Tex::decode_wrapmode

(

name

)

OIIO_API void Tex::parse_wrapmodes	(	const char *	wrapmodes,
		Wrap &	swrapcode,
		Wrap &	twrapcode
	)

Utility: Parse a single wrap mode (e.g., "periodic") or a comma-separated wrap modes string (e.g., "black,clamp") into separate Wrap enums for s and t.

Variable Documentation

OIIO_INLINE_CONSTEXPR int Tex::BatchAlign = BatchWidth * sizeof(float)

Definition at line 138 of file texture.h.

OIIO_INLINE_CONSTEXPR int Tex::BatchWidth = OIIO_TEXTURE_SIMD_BATCH_WIDTH

The SIMD width for batched texturing operations. This is fixed within any release of OpenImageIO, but may change from release to release and also may be overridden at build time. A typical batch size is 16.

OIIO_INLINE_CONSTEXPR RunMask Tex::RunMaskOn = 0xffff
