Field Summary

Fields

Modifier and Type	Field and Description
int[]	addressMode Specifies the addressing mode, that is how out-of-range texture coordinates are handled. addressMode is an array of size three whose first, second, and third elements specify the addressing mode for the first, second, and third texture coordinates, respectively; the addressing mode is equal to either cudaAddressModeClamp, in which case out-of-range texture coordinates are clamped to the valid range, or cudaAddressModeWrap, in which case out-of range texture coordinates are wrapped to the valid range; cudaAddressModeWrap is only supported for normalized texture coordinates;
cudaChannelFormatDesc	channelDesc Describes the format of the value that is returned when fetching the texture.
int	disableTrilinearOptimization Disable any trilinear filtering optimizations.
int	filterMode Specifies the filtering mode, that is how the value returned when fetching the texture is computed based on the input texture coordinates.
int	maxAnisotropy Limit to the anisotropy ratio
float	maxMipmapLevelClamp Upper end of the mipmap level range to clamp access to
float	minMipmapLevelClamp Lower end of the mipmap level range to clamp access to
int	mipmapFilterMode Mipmap filter mode
float	mipmapLevelBias Offset applied to the supplied mipmap level
int	normalized Specifies whether texture coordinates are normalized or not.
int	sRGB Perform sRGB->linear conversion during texture read

Field Detail

normalized

public int normalized

Specifies whether texture coordinates are normalized or not. If it is non-zero, all elements in the texture are addressed with texture coordinates in the range [0,1] rather than in the range [0,width-1], [0,height-1], or [0,depth-1] where width, height, and depth are the texture sizes;

filterMode

public int filterMode

Specifies the filtering mode, that is how the value returned when fetching the texture is computed based on the input texture coordinates. filterMode is equal to cudaFilterModePoint or cudaFilterModeLinear; if it is cudaFilterModePoint, the returned value is the texel whose texture coordinates are the closest to the input texture coordinates; if it is cudaFilterModeLinear, the returned value is the linear interpolation of the two (for a one-dimensional texture), four (for a two-dimensional texture), or eight (for a three-dimensional texture) texels whose texture coordinates are the closest to the input texture coordinates; cudaFilterModeLinear is only valid for returned values of floating-point type;

addressMode

public int[] addressMode

Specifies the addressing mode, that is how out-of-range texture coordinates are handled. addressMode is an array of size three whose first, second, and third elements specify the addressing mode for the first, second, and third texture coordinates, respectively; the addressing mode is equal to either cudaAddressModeClamp, in which case out-of-range texture coordinates are clamped to the valid range, or cudaAddressModeWrap, in which case out-of range texture coordinates are wrapped to the valid range; cudaAddressModeWrap is only supported for normalized texture coordinates;
