Detailed Documentation

Properties

ISemanticBuffer AwarenessBuffer

The CPU copy of the latest awareness buffer.

uint ChannelCount

The number of classes available.

string[] Channels

Returns the possible semantic classes that a pixel can be interpreted.

Methods

void CopyToAlignedTextureARGB32(
    int channel,
    ref Texture2D texture,
    ScreenOrientation orientation
)

Pushes the current state of the semantics buffer to the specified target texture. The resulting texture will contain a display aligned representation of the specified channel.

注釈

Only use this call if you absolutely need the texture to be display aligned. It is faster to create a texture from the awareness buffer itself.

Parameters:

channel	The semantic channel index to create a texture of.
texture	The target texture. If this texture does not exist, it will be created. It is the responsibility of the caller to release this texture.
orientation	The target orientation of the texture. This determines the resolution of the container. This has to be either landscape or portrait.

void CopyToAlignedTextureARGB32(
    int[] channels,
    ref Texture2D texture,
    ScreenOrientation orientation
)

Pushes the current state of the semantics buffer to the specified target texture. The resulting texture will contain a display aligned representation of the specified channels.

Parameters:

channels	The semantic channel indices to create a texture of.
texture	The target texture. If this texture does not exist, it will be created. It is the responsibility of the caller to release this texture.
orientation	The target orientation of the texture. This determines the resolution of the container. This has to be either landscape or portrait.

bool DoesChannelExistAt(int viewportX, int viewportY, int channelIndex)

Check if a pixel is of a certain semantics class.

Parameters:

viewportX	Horizontal coordinate in viewport space.
viewportY	Vertical coordinate in viewport space.
channelIndex	Channel index of the semantic class to look for.

Returns:

True if the semantic channel exists at the given coordinates.

bool DoesChannelExistAt(int viewportX, int viewportY, string channelName)

Check if a pixel is of a certain semantics class.

Parameters:

viewportX	Horizontal coordinate in viewport space.
viewportY	Vertical coordinate in viewport space.
channelName	Name of the semantic class to look for.

Returns:

True if the semantic channel exists at the given coordinates.

int[] GetChannelIndicesAt(int viewportX, int viewportY)

Returns an array of channel indices that are present for the specified pixel.

注釈

This query allocates garbage.

Parameters:

viewportX	Horizontal coordinate in viewport space.
viewportY	Vertical coordinate in viewport space.

Returns:

An array of channel indices present for the pixel.

string[] GetChannelNamesAt(int viewportX, int viewportY)

Returns an array of channel names that are present for the specified pixel.

注釈

This query allocates garbage.

Parameters:

viewportX	Horizontal coordinate in viewport space.
viewportY	Vertical coordinate in viewport space.

Returns:

An array of channel names present for the pixel.

uint GetSemantics(int viewportX, int viewportY)

Returns the semantics of the specified pixel.

Parameters:

viewportX	Horizontal coordinate in viewport space.
viewportY	Vertical coordinate in viewport space.

Returns:

The result is a 32-bit packed unsigned integer where each bit is a binary indicator for a class.
