Shader (GPU-side) data type for 64-bit floating point values.
Use this type inside shader code as a counterpart of CPU-side double type.
This is a r-value type. You must initialize it with value, either CPU-side one (an explicit constant), or an expression computed on GPU side. The value can not be changed.
For mutable variable type, see VDouble. Beware that mutable variables can degrade performance on GPU, therefore Double is preferable, unless you really want a mutable variable.
vpp::Double::Double | ( | double | value | ) |
Construct a r-value from specified C++ value.
The source value can be either a constant, or a parameter passed to shader specific for that shader. The constructor is called once when compiling the pipeline.
