Methods

ApplyAndDestroySyncPacket

void ApplyAndDestroySyncPacket(FrameAllocator &allocator, const MaterialParameters::SyncPacket &syncPacket)

Updates the stored parameters from the provided sync packet, allowing changes to be transfered between core objects and render proxies.

Packet must be retrieved from b3d::MaterialParams::CreateSyncPacket(). Sync packet is destroyed using the provided allocator after it has been applied.

GetStructData

void GetStructData(const String &name, void *value, u32 size, u32 arrayIdx) const

Returns the value of a shader structure parameter with the specified name at the specified array index.

If the parameter name, index or type is not valid a warning will be logged and output value will not be retrieved.

name
Name of the shader parameter.
value
Pre-allocated buffer of bytes where the value will be retrieved.
size
Size of the buffer into which to write the value. Must match parameter struct's size.
arrayIdx
If the parameter is an array, index of the entry to access.

SetStructData

void SetStructData(const String &name, const void *value, u32 size, u32 arrayIdx)

Sets the value of a shader structure parameter with the specified name at the specified array index.

If the parameter name, index or type is not valid a warning will be logged and output value will not be retrieved.

name
Name of the shader parameter.
value
Buffer of bytes containing the new value of the structure.
size
Size of the buffer from which to retrieve the value. Must match parameter struct's size.
arrayIdx
If the parameter is an array, index of the entry to access.

GetTexture

void GetTexture(const String &name, TextureType &value, TextureSurface &surface) const

Returns the value of a shader texture parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be retrieved.

name
Name of the shader parameter.
value
Output value of the parameter.
surface
Surface describing which part of the texture is being accessed.

SetTexture

void SetTexture(const String &name, const TextureType &value, const TextureSurface &surface = TextureSurface::kComplete)

Sets the value of a shader texture parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be set.

name
Name of the shader parameter.
value
New value of the parameter.
surface
Surface describing which part of the texture is being accessed.

GetSpriteImage

void GetSpriteImage(const String &name, SpriteImageType &value) const

Returns the value of a shader texture parameter with the specified name as a sprite image.

If the parameter name or type is not valid a warning will be logged and output value will not be retrieved. If the assigned texture is not a sprite texture then this returns null and you should use one of the GetTexture() overloads instead.

name
Name of the shader parameter.
value
Output value of the parameter.

SetSpriteImage

void SetSpriteImage(const String &name, const SpriteImageType &value)

Assigns a sprite image to a shader texture parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be set.

name
Name of the shader parameter.
value
New value of the parameter.

GetStorageTexture

void GetStorageTexture(const String &name, TextureType &value, TextureSurface &surface) const

Returns the value of a shader load/store texture parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be retrieved.

name
Name of the shader parameter.
value
Output value of the parameter.
surface
Surface describing which part of the texture is being accessed.

SetStorageTexture

void SetStorageTexture(const String &name, const TextureType &value, const TextureSurface &surface)

Sets the value of a shader load/store texture parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and the value will not be set.

name
Name of the shader parameter.
value
New value of the parameter.
surface
Surface describing which part of the texture is being accessed.

GetBuffer

void GetBuffer(const String &name, BufferType &value) const

Returns the value of a shader buffer parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be retrieved.

name
Name of the shader parameter.
value
Output value of the parameter.

SetBuffer

void SetBuffer(const String &name, const BufferType &value)

Sets the value of a shader buffer parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be set.

name
Name of the shader parameter.
value
New value of the parameter.

GetSamplerState

void GetSamplerState(const String &name, SPtr<SamplerState> &value) const

Sets the value of a shader sampler state parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be set.

name
Name of the shader parameter.
value
Output value of the parameter.

SetSamplerState

void SetSamplerState(const String &name, const SPtr<SamplerState> &value)

Sets the value of a shader sampler state parameter with the specified name.

If the parameter name or type is not valid a warning will be logged and output value will not be set.

name
Name of the shader parameter.
value
New value of the parameter.

IsAnimated

bool IsAnimated(const String &name, u32 arrayIdx = 0)

Checks does the data parameter with the specified name currently contains animated data.

This could be an animation curve or a color gradient.

GetStructSize

u32 GetStructSize(const ParamData &param) const

Returns a size of a struct parameter in bytes, using the internal parameter reference.

Caller must guarantee the parameter reference is valid and belongs to this object.

GetTextureType

MateralParamTextureType GetTextureType(const ParamData &param) const

Returns the type of texture that is currently assigned to the provided parameter.

This can only be called on on texture parameters. Caller must guarantee the parameter reference is valid, is of a texture type and belongs to this object.

GetOwningSpriteImage

SpriteImageType GetOwningSpriteImage(const ParamData &param) const

Returns a sprite texture that is used for populating the specified data parameter.

This is only relevant for data parameters marked with the ShaderParamAttributeType::SpriteUV attribute.

GetDefaultTexture

void GetDefaultTexture(const ParamData &param, TextureType &value) const

Returns the default texture (one assigned when no other is provided), if available for the specified parameter.

Parameter is represented using the internal parameter reference and the caller must guarantee the parameter eference is valid and belongs to this object.

GetDefaultSamplerState

void GetDefaultSamplerState(const ParamData &param, SPtr<SamplerState> &value) const

Returns the default sampler state (one assigned when no other is provided), if available for the specified parameter.

Parameter is represented using the internal parameter reference and the caller must guarantee the parameter reference is valid and belongs to this object.
