Samplers

Defines

EQU(field)

CMP(field)

FOR_EACH_FIELD(op, sep)

Enums

enum [anonymous]

MipMapMode enum.

Values:

enumerator TEXMIPMAP_DEFAULT: driver default

enumerator TEXMIPMAP_NONE: no mipmapping

enumerator TEXMIPMAP_POINT: point mipmapping

enumerator TEXMIPMAP_LINEAR: linear mipmapping

namespace d3d

Enums

enum class MipMapMode : uint32_t

MipMapMode enum class.

Values:

enumerator Default: [DEPRECATED] driver default

enumerator Disabled: [DEPRECATED] no mipmapping

enumerator Point: point mipmapping

enumerator Linear: linear mipmapping

enum class FilterMode : uint32_t

FilterMode enum class.

Values:

enumerator Default: [DEPRECATED] driver default

enumerator Disabled: [DEPRECATED]

enumerator Point: point sampling

enumerator Linear: linear sampling

enumerator Best: [DEPRECATED] anisotropic and similar, if available

enumerator Compare: point comparasion for using in pcf

enum class AddressMode : uint32_t

AddressMode enum class.

Values:

enumerator Wrap: Repeats the texture when texture coordinates are outside [0, 1].

enumerator Mirror: Mirrors the texture when texture coordinates are outside [0, 1].

enumerator Clamp: Clamps texture coordinates to [0, 1].

enumerator Border: Uses the border color when texture coordinates are outside [0, 1].

enumerator MirrorOnce: Similar to Mirror and Clamp. Takes the absolute value of the texture coordinate (thus, mirroring around 0), and then clamps to the maximum value. The most common usage is for volume textures, where support for the full MirrorOnce texture-addressing mode is not necessary, but the data is symmetrical around the one axis.

Functions

SamplerHandle request_sampler(const SamplerInfo &sampler_info)

Request a sampler handle with the given sampler info.

Creates a sampler, when necessary. Identical infos should yield identical handles. This call is thread-safe and does not require external synchronization.

Parameters:: sampler_info – The information needed to create the sampler
Returns:: SamplerHandle The handle to the sampler

void set_sampler(unsigned shader_stage, unsigned slot, SamplerHandle sampler)

Binds given sampler to the slot.

This call is not thread-safe, requires global gpu lock to be held

Parameters:

shader_stage – The shader stage to bind the sampler to. One of STAGE_XXX enum.
slot – The slot to bind the sampler to
sampler – The handle to the sampler to be bound

struct BorderColor

BorderColor struct.

Public Types

enum class Color : UnderlyingT 

Values:

enumerator TransparentBlack: Transparent black color.

enumerator OpaqueBlack: Opaque black color.

enumerator OpaqueWhite: Opaque white color.

using UnderlyingT = uint32_t

Public Functions

inline BorderColor(Color color = Color::TransparentBlack)

inline operator E3DCOLOR() const

inline operator UnderlyingT() const

Public Members

enum d3d::BorderColor::Color color

struct SamplerInfo

SamplerInfo struct.

This struct contains the information needed to create a sampler

Public Functions
