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 125 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 128 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 104 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	Stochastic trilinear.
StochasticAniso	Stochastic anisotropic.

Definition at line 92 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!

Function Documentation

OIIO_API Wrap Tex::decode_wrapmode

(

const char *

name

)

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

OIIO_API Wrap Tex::decode_wrapmode

(

ustring

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.
