Member Function Documentation

bool RV_ShaderBindFuncs::bindDouble ( const UT_StringRef &  name,
fpreal64  v,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Bind a single double value. GPU must support native FP64 values.

bool RV_ShaderBindFuncs::bindDoubles ( const UT_StringRef &  name,
const fpreal64 *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Set values for a fixed-length double array.

bool RV_ShaderBindFuncs::bindDVector3 ( const UT_StringRef &  name,
const fpreal64 *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

bind a series of dvec3s, using std140 packing (padded to ivec4)

bool RV_ShaderBindFuncs::bindFloat ( const UT_StringRef &  name,
fpreal32  v,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Bind a single float value.

bool RV_ShaderBindFuncs::bindFloats ( const UT_StringRef &  name,
const fpreal32 *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Set values for a fixed-length float array.

bool RV_ShaderBindFuncs::bindInt ( const UT_StringRef &  name,
int  v,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Copy the data for uniform 'name' into the buffer. If name does not exist in the buffer, or its type/array size doesn't match, bind...() will return false. If its value is not different from the current value in the block, it will not cause an upload. Shader Storage Blocks can have open-ended arrays, and variables within those arrays can specify their array index with 'array_index'.

bool RV_ShaderBindFuncs::bindInts ( const UT_StringRef &  name,
const int *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Set values for a fixed-length integer array.

bool RV_ShaderBindFuncs::bindIntVector3 ( const UT_StringRef &  name,
const int *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

bind a series of ivec3s, using std140 packing (padded to ivec4)

vec3 is a little different, as it is padded to vec4 in uniform blocks. SSBOs with std420 packing should use bindVector().

bool RV_ShaderBindFuncs::bindMatrix ( const UT_StringRef &  name,
const UT_Matrix2F &  m,
int  array_index = 0,

Set a single 4x4 matrix value.

bool RV_ShaderBindFuncs::bindMatrix ( const UT_StringRef &  name,

Set a single 3x3 matrix value (dmat3).

bool RV_ShaderBindFuncs::bindMatrix ( const UT_StringRef &  name,
const UT_Matrix4D &  m,

Set a single 4x4 matrix value (dmat4).

bool RV_ShaderBindFuncs::bindUint64 ( const UT_StringRef &  name,
uint64  v,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Bind a single handle value to a sampler. GPU must support bindless textures.

bool RV_ShaderBindFuncs::bindUint64s ( const UT_StringRef &  name,
const uint64 *  valarray,
int  array_size,
int  array_index = 0,
int *  opt_idx = nullptr 
)

Set values for a uint64 handle array.

)

Set the value of the uniform 'name' with a block of memory.

const UT_Vector2F &  v,
int  array_index = 0,
