Creates a call to the continuation callable program at the specified SBT entry.
This will call the program that was specified in the OptixProgramGroupCallables::entryFunctionNameCC in the module specified by OptixProgramGroupCallables::moduleCC.
The address of the SBT entry is calculated by: OptixShaderBindingTable::callablesRecordBase + ( OptixShaderBindingTable::callablesRecordStrideInBytes * sbtIndex ).
As opposed to direct callable programs, continuation callable programs are allowed to make secondary optixTrace calls.
Behavior is undefined if there is no continuation callable program at the specified SBT entry.
Behavior is undefined if the number of arguments that are being passed in does not match the number of parameters expected by the program that is called. In validation mode an exception will be generated.
| [in] | sbtIndex | The offset of the SBT entry of the continuation callable program to call relative to OptixShaderBindingTable::callablesRecordBase. |
| [in] | args | The arguments to pass to the continuation callable program. |
Available in RG, CH, MS, CC

Creates a call to the direct callable program at the specified SBT entry.
This will call the program that was specified in the OptixProgramGroupCallables::entryFunctionNameDC in the module specified by OptixProgramGroupCallables::moduleDC.
The address of the SBT entry is calculated by: OptixShaderBindingTable::callablesRecordBase + ( OptixShaderBindingTable::callablesRecordStrideInBytes * sbtIndex ).
Direct callable programs are allowed to call optixTrace, but any secondary trace calls invoked from subsequently called CH, MS and callable programs will result an an error.
Behavior is undefined if there is no direct callable program at the specified SBT entry.
Behavior is undefined if the number of arguments that are being passed in does not match the number of parameters expected by the program that is called. In validation mode an exception will be generated.
| [in] | sbtIndex | The offset of the SBT entry of the direct callable program to call relative to OptixShaderBindingTable::callablesRecordBase. |

Return the object space curve control vertex data of a CatmullRom spline curve in a Geometry Acceleration Structure (GAS) at a given motion time.
To access vertex data, the GAS must be built using the flag OPTIX_BUILD_FLAG_ALLOW_RANDOM_VERTEX_ACCESS.
data[i] = {x,y,z,w} with {x,y,z} the position and w the radius of control vertex i.
If motion is disabled via OptixPipelineCompileOptions::usesMotionBlur, or the GAS does not contain motion, the time parameter is ignored.
Available in all OptiX program types

Use optixGetPrimitiveType() to interpret the hit kind. For custom intersections (primitive type OPTIX_PRIMITIVE_TYPE_CUSTOM), this is the 7-bit hitKind passed to optixReportIntersection(). Hit kinds greater than 127 are reserved for built-in primitives.

Returns the OPTIX_DEVICE_PROPERTY_LIMIT_MAX_INSTANCE...">OptixInstance::instanceId of the instance within the top level acceleration structure associated with the current intersection.
When building an acceleration structure using OptixBuildInputInstanceArray each OptixInstance has a user supplied instanceId. OptixInstance objects reference another acceleration structure. During traversal the acceleration structures are visited top down. In the IS and AH programs the OPTIX_DEVICE_PROPERTY_LIMIT_MAX_INSTANCE...">OptixInstance::instanceId corresponding to the most recently visited OptixInstance is returned when calling optixGetInstanceId().

In the case where there is no OptixInstance visited, optixGetInstanceId returns 0

optixTexFootprint2D calculates the footprint of a corresponding 2D texture fetch (non-mipmapped).
On Turing and subsequent architectures, a texture footprint instruction allows user programs to determine the set of texels that would be accessed by an equivalent filtered texture lookup.
| [in] | tex | CUDA texture object (cast to 64-bit integer) |
| [in] | texInfo | Texture info packed into 32-bit integer, described below. |
| [in] | x | Texture coordinate |
| [in] | y | Texture coordinate |
| [out] | singleMipLevel | Result indicating whether the footprint spans only a single miplevel. |
The texture info argument is a packed 32-bit integer with the following layout:
texInfo[31:29] = reserved (3 bits) texInfo[28:24] = miplevel count (5 bits) texInfo[23:20] = log2 of tile width (4 bits) texInfo[19:16] = log2 of tile height (4 bits) texInfo[15:10] = reserved (6 bits) texInfo[9:8] = horizontal wrap mode (2 bits) (CUaddress_mode) texInfo[7:6] = vertical wrap mode (2 bits) (CUaddress_mode) texInfo[5] = mipmap filter mode (1 bit) (CUfilter_mode) texInfo[4:0] = maximum anisotropy (5 bits)
Returns a 16-byte structure (as a uint4) that stores the footprint of a texture request at a particular "granularity", which has the following layout:
struct Texture2DFootprint { unsigned long long mask; unsigned int tileY : 12; unsigned int reserved1 : 4; unsigned int dx : 3; unsigned int dy : 3; unsigned int reserved2 : 2; unsigned int granularity : 4; unsigned int reserved3 : 4; unsigned int tileX : 12; unsigned int level : 4; unsigned int reserved4 : 16; };
The granularity indicates the size of texel groups that are represented by an 8x8 bitmask. For example, a granularity of 12 indicates texel groups that are 128x64 texels in size. In a footprint call, The returned granularity will either be the actual granularity of the result, or 0 if the footprint call was able to honor the requested granularity (the usual case).
level is the mip level of the returned footprint. Two footprint calls are needed to get the complete footprint when a texture call spans multiple mip levels.
mask is an 8x8 bitmask of texel groups that are covered, or partially covered, by the footprint. tileX and tileY give the starting position of the mask in 8x8 texel-group blocks. For example, suppose a granularity of 12 (128x64 texels), and tileX=3 and tileY=4. In this case, bit 0 of the mask (the low order bit) corresponds to texel group coordinates (3*8, 4*8), and texel coordinates (3*8*128, 4*8*64), within the specified mip level.
If nonzero, dx and dy specify a "toroidal rotation" of the bitmask. Toroidal rotation of a coordinate in the mask simply means that its value is reduced by 8. Continuing the example from above, if dx=0 and dy=0 the mask covers texel groups (3*8, 4*8) to (3*8+7, 4*8+7) inclusive. If, on the other hand, dx=2, the rightmost 2 columns in the mask have their x coordinates reduced by 8, and similarly for dy.
See the OptiX SDK for sample code that illustrates how to unpack the result.

Throws a user exception with the given exception code (overload without exception details).
The exception code must be in the range from 0 to 2^30 - 1. Up to 8 optional exception details can be passed. They can be queried in the EX program using optixGetExceptionDetail_0() to ..._8().
The exception details must not be used to encode pointers to the stack since the current stack is not preserved in the EX program.
Not available in EX

Similar to optixTrace, but does not invoke closesthit or miss. Instead, it overwrites the current outgoing hit object with the results of traversing the ray. The outgoing hit object may be invoked at some later point with optixInvoke. The outgoing hit object can also be queried through various functions such as optixHitObjectIsHit or optixHitObjectGetAttribute_0.
