Member Enumeration Documentation

enum TextureOptions::InterpMode

Interp mode determines how we sample within a mipmap level

Enumerator
InterpClosest	Force closest texel.
InterpBilinear	Force bilinear lookup within a mip level.
InterpBicubic	Force cubic lookup within a mip level.
InterpSmartBicubic	Bicubic when magnifying, else bilinear.

Definition at line 387 of file texture.h.

enum TextureOptions::MipMode

Mip mode determines if/how we use mipmaps

Enumerator
MipModeDefault	Default high-quality lookup.
MipModeNoMIP	Just use highest-res image, no MIP mapping.
MipModeOneLevel	Use just one mipmap level.
MipModeTrilinear	Use two MIPmap levels (trilinear)
MipModeAniso	Use two MIPmap levels w/ anisotropic.

Definition at line 377 of file texture.h.

enum TextureOptions::Wrap

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

Enumerator
WrapDefault	Use the default found in the file.
WrapBlack	Black outside [0..1].
WrapClamp	Clamp to [0..1].
WrapPeriodic	Periodic mod 1.
WrapMirror	Mirror the image.
WrapPeriodicPow2	Periodic, but only for powers of 2!!!
WrapPeriodicSharedBorder	Periodic with shared border (env)
WrapLast	Mark the end – don't use this!

static void TextureOptions::parse_wrapmodes	(	const char *	wrapmodes,
		TextureOptions::Wrap &	swrapcode,
		TextureOptions::Wrap &	twrapcode
	)

inlinestatic

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.
