OptiX Utilities.
|
inline |
Loads the OptiX library and initializes the function table used by the stubs below.
A variant of optixInitWithHandle() that does not make the handle to the loaded library available.
|
inline |
Loads the OptiX library and initializes the function table used by the stubs below.
If handlePtr is not nullptr, an OS-specific handle to the library will be returned in *handlePtr.
|
inline |
Unloads the OptiX library and zeros the function table used by the stubs below. Takes the handle returned by optixInitWithHandle. All OptixDeviceContext objects must be destroyed before calling this function, or the behavior is undefined.
|
inline |
Retrieves direct and continuation stack sizes for each program in the program group and accumulates the upper bounds in the correponding output variables based on the semantic type of the program. Before the first invocation of this function with a given instance of OptixStackSizes, the members of that instance should be set to 0. If the programs rely on external functions, passing the current pipeline will consider these as well. Otherwise, a null pointer can be passed instead. When external functions are present, a warning will be issued for these cases.

Computes the stack size values needed to configure a pipeline.
This variant is a specialization of optixUtilComputeStackSizes() for a simple path tracer with the following assumptions: There are only two ray types, camera rays and shadow rays. There are only RG, MS, and CH programs, and no AH, IS, CC, or DC programs. The camera rays invoke only the miss and closest hit programs MS1 and CH1, respectively. The CH1 program might trace shadow rays, which invoke only the miss and closest hit programs MS2 and CH2, respectively.
For flexibility, we allow for each of CH1 and CH2 not just one single program group, but an array of programs groups, and compute the maximas of the stack size requirements per array.
See programming guide for an explanation of the formula.
If the programs rely on external functions, passing the current pipeline will consider these as well. Otherwise, a null pointer can be passed instead. When external functions are present, a warning will be issued for these cases.

Run denoiser on input layers see optixDenoiserInvoke additional parameters:
Runs the denoiser on the input layers on a single GPU and stream using optixDenoiserInvoke. If the input layers' dimensions are larger than the specified tile size, the image is divided into tiles using optixUtilDenoiserSplitImage, and multiple back-to-back invocations are performed in order to reuse the scratch space. Multiple tiles can be invoked concurrently if optixUtilDenoiserSplitImage is used directly and multiple scratch allocations for each concurrent invocation are used. The input parameters are the same as optixDenoiserInvoke except for the addition of the maximum tile size.
