| typedef struct OptixBuildInputCurveArray OptixBuildInputCurveArray |
Curve inputs.
A curve is a swept surface defined by a 3D spline curve and a varying width (radius). A curve (or "strand") of degree d (3=cubic, 2=quadratic, 1=linear) is represented by N > d vertices and N width values, and comprises N - d segments. Each segment is defined by d+1 consecutive vertices. Each curve may have a different number of vertices.
OptiX describes the curve array as a list of curve segments. The primitive id is the segment number. It is the user's responsibility to maintain a mapping between curves and curve segments. Each index buffer entry i = indexBuffer[primid] specifies the start of a curve segment, represented by d+1 consecutive vertices in the vertex buffer, and d+1 consecutive widths in the width buffer. Width is interpolated the same way vertices are interpolated, that is, using the curve basis.
Each curves build input has only one SBT record. To create curves with different materials in the same BVH, use multiple build inputs.
Custom primitive inputs.

The vertex buffers and radius buffers point to a host array of device pointers, one per motion step. Host array size must match the number of motion keys as set in OptixMotionOptions (or an array of size 1 if OptixMotionOptions::numKeys is set to 0 or 1). Each per motion key device pointer must point to an array of vertices corresponding to the center points of the spheres, or an array of 1 or N radii. Format OPTIX_VERTEX_FORMAT_FLOAT3 is used for vertices, OPTIX_VERTEX_FORMAT_FLOAT for radii.

The context and/or OptiX itself might no longer be in a usable state. 2 error A recoverable error, e.g., when passing invalid call parameters. 3 warning Hints that OptiX might not behave exactly as requested by the user or may perform slower than expected. 4 print Status or progress messages.

| typedef struct OptixMatrixMotionTransform OptixMatrixMotionTransform |
Represents a matrix motion transformation.
The device address of instances of this type must be a multiple of OPTIX_TRANSFORM_BYTE_ALIGNMENT.

| typedef struct OptixMicromapBuffers OptixMicromapBuffers |

| typedef struct OptixMicromapBufferSizes OptixMicromapBufferSizes |

| typedef struct OptixModule_t* OptixModule |
Opaque type representing a module.
Struct for specifying specializations for pipelineParams as specified in OptixPipelineCompileOptions::pipelineLaunchParamsVariableName.
The bound values are supposed to represent a constant value in the pipelineParams. OptiX will attempt to locate all loads from the pipelineParams and correlate them to the appropriate bound value, but there are cases where OptiX cannot safely or reliably do this. For example if the pointer to the pipelineParams is passed as an argument to a non-inline function or the offset of the load to the pipelineParams cannot be statically determined (e.g. accessed in a loop). No module should rely on the value being specialized in order to work correctly. The values in the pipelineParams specified on optixLaunch should match the bound value. If validation mode is enabled on the context, OptiX will verify that the bound values specified matches the values in pipelineParams specified to optixLaunch.
These values are compiled in to the module as constants. Once the constants are inserted into the code, an optimization pass will be run that will attempt to propagate the consants and remove unreachable code.
If caching is enabled, changes in these values will result in newly compiled modules.
The pipelineParamOffset and sizeInBytes must be within the bounds of the pipelineParams variable. OPTIX_ERROR_INVALID_VALUE will be returned from optixModuleCreateFromPTX otherwise.
If more than one bound value overlaps or the size of a bound value is equal to 0, an OPTIX_ERROR_INVALID_VALUE will be returned from optixModuleCreateFromPTX.
The same set of bound values do not need to be used for all modules in a pipeline, but overlapping values between modules must have the same value. OPTIX_ERROR_INVALID_VALUE will be returned from optixPipelineCreate otherwise.
| typedef struct OptixModuleCompileOptions OptixModuleCompileOptions |

| typedef enum OptixModuleCompileState OptixModuleCompileState |

| typedef struct OptixOpacityMicromapUsageCount OptixOpacityMicromapUsageCount |
Opacity micromap usage count for acceleration structure builds. Specifies how many opacity micromaps of a specific type are referenced by triangles when building the AS. Note that while this is similar to OptixOpacityMicromapHistogramEntry, the usage count specifies how many opacity micromaps of a specific type are referenced by triangles in the AS.
| typedef enum OptixPayloadSemantics OptixPayloadSemantics |
Semantic flags for a single payload word.
Used to specify the semantics of a payload word per shader type. "read": Shader of this type may read the payload word. "write": Shader of this type may write the payload word.
"trace_caller_write": Shaders may consume the value of the payload word passed to optixTrace by the caller. "trace_caller_read": The caller to optixTrace may read the payload word after the call to optixTrace.
Semantics can be bitwise combined. Combining "read" and "write" is equivalent to specifying "read_write". A payload needs to be writable by the caller or at least one shader type. A payload needs to be readable by the caller or at least one shader type after a being writable.
| typedef struct OptixPayloadType OptixPayloadType |
Specifies a single payload type.

| typedef struct OptixShaderBindingTable OptixShaderBindingTable |
Describes the shader binding table (SBT)
| typedef struct OptixSRTData OptixSRTData |
Represents an SRT transformation.
An SRT transformation can represent a smooth rotation with fewer motion keys than a matrix transformation. Each motion key is constructed from elements taken from a matrix S, a quaternion R, and a translation T.
The scaling matrix \(S = \begin{bmatrix} sx & a & b & pvx \\ 0 & sy & c & pvy \\ 0 & 0 & sz & pvz \end{bmatrix}\) defines an affine transformation that can include scale, shear, and a translation. The translation allows to define the pivot point for the subsequent rotation.
The quaternion R = [ qx, qy, qz, qw ] describes a rotation with angular component qw = cos(theta/2) and other components [ qx, qy, qz ] = sin(theta/2) * [ ax, ay, az ] where the axis [ ax, ay, az ] is normalized.
The translation matrix \(T = \begin{bmatrix} 1 & 0 & 0 & tx \\ 0 & 1 & 0 & ty \\ 0 & 0 & 1 & tz \end{bmatrix}\) defines another translation that is applied after the rotation. Typically, this translation includes the inverse translation from the matrix S to reverse the translation for the pivot point for R.
To obtain the effective transformation at time t, the elements of the components of S, R, and T will be interpolated linearly. The components are then multiplied to obtain the combined transformation C = T * R * S. The transformation C is the effective object-to-world transformations at time t, and C^(-1) is the effective world-to-object transformation at time t.

The device address of instances of this type must be a multiple of OPTIX_TRANSFORM_BYTE_ALIGNMENT.

Semantic flags for a single payload word.
Used to specify the semantics of a payload word per shader type. "read": Shader of this type may read the payload word. "write": Shader of this type may write the payload word.
"trace_caller_write": Shaders may consume the value of the payload word passed to optixTrace by the caller. "trace_caller_read": The caller to optixTrace may read the payload word after the call to optixTrace.
Semantics can be bitwise combined. Combining "read" and "write" is equivalent to specifying "read_write". A payload needs to be writable by the caller or at least one shader type. A payload needs to be readable by the caller or at least one shader type after a being writable.

However, an 16-byte stride (and buffer alignment) is recommended for vertices of format OPTIX_VERTEX_FORMAT_FLOAT3 for GAS build performance.
