RPR SDK 3.01.00 - 24 February 2023

## NORTHSTAR :

RPR-1170 - (Bug) - Fix out of memory crash when large scene rendering

RPR-1135 - (Feature) - Camera offset supports texture map ( rprCameraSetUVDistortion )

RPR-1122 - (Bug) - Improve refraction quality

* Support of new RPR_MATERIAL_NODE_OP_**** arthmetics: EXP, ROTATE2D, ROTATE3D, NOP, CEIL, ROUND, SIGN, SQRT, CLAMP.

* For Northstar, the default render backend is now HIP ( instead of OpenCL ).

The main difference is that compute kernels are now precompiled by us. They must be downloaded from a separate link.

Check the readme for more information.

For now you can still use the OpenCL backend ( with RPR_CREATION_FLAGS_ENABLE_OPENCL in rprCreateContext ).

However we don't recommend it as in the future we may put less resource to support this backend.

## NORTHSTAR :

RPR-1073 - (Bug) - Fix darkening issue of toon shader with transparency

RPR-1072 - (Bug) - Fix emission with transparency casts incorrect shadow

RPR-1068 - (Bug) - Fix reflection catcher doesn't catch emission

RPR-1062 - (Task) - Expose ObjectID aov in RPR API as integer type

RPR-1042 - (Task) - Absortion support for thin surfaces

RPR-1008 - (Task) - Extend cryptomatte for reflection

RPR-1005 - (Task) - Add progress callback for better logging with scene update, cache creation and render time

RPR-275 - (Task) - Add pixel filter support ( Anti-aliasing )

## RPR API :

* Those context parameter have been removed :

RPR_CONTEXT_IMAGE_FILTER_BOX_RADIUS

RPR_CONTEXT_IMAGE_FILTER_GAUSSIAN_RADIUS

RPR_CONTEXT_IMAGE_FILTER_TRIANGLE_RADIUS

RPR_CONTEXT_IMAGE_FILTER_MITCHELL_RADIUS

RPR_CONTEXT_IMAGE_FILTER_LANCZOS_RADIUS

RPR_CONTEXT_IMAGE_FILTER_BLACKMANHARRIS_RADIUS

and replaced by a single parameter : RPR_CONTEXT_IMAGE_FILTER_RADIUS.

* typo fixed: RPR_CONTEXT_RAY_CAST_EPISLON --> RPR_CONTEXT_RAY_CAST_EPSILON

* 3 new callbacks has been added to improve the measure of performance :

RPR_CONTEXT_UPDATE_TIME_CALLBACK_* --> get the time it took to update/compile the scene inside the core rendering engine.

RPR_CONTEXT_RENDER_TIME_CALLBACK_* --> get the time it took to run the actual rendering operation.

RPR_CONTEXT_FIRST_ITERATION_TIME_CALLBACK_* --> get the time it took to run the first rendering iteration. This time could he higher than next iteration as first iteration is creating some cache.

First iteration time callback is only called when a rendering is done from a cleared framebuffer.

Those callbacks are triggered during the rprContextRender / rprContextRenderTile calls.

They have the same structure than the already existing RPR_CONTEXT_RENDER_UPDATE_CALLBACK_* meaning : void callback( float , void* )

First argument is time in milliseconds, second argument is RPR_CONTEXT_***_CALLBACK_DATA.

example:

void updateTimeCallback( float timems, void* userData ) { *((float*)userData) = timems; }

float updateTimeFromCallback = 0.0f;

rprContextSetParameterByKeyPtr(ctxt, RPR_CONTEXT_UPDATE_TIME_CALLBACK_FUNC, (void*)updateTimeCallback);

rprContextSetParameterByKeyPtr(ctxt, RPR_CONTEXT_UPDATE_TIME_CALLBACK_DATA, &updateTimeFromCallback);

* A new RPR_MATERIAL_NODE_RAMP node has been exposed. This Ramp can use N control points and we can change the interpolation type.

A tutorial demo will be added in the future to illustrate this feature.

* New "visibility" flag: RPR_SHAPE_VISIBILITY_RECEIVE_SHADOW / RPR_CURVE_VISIBILITY_RECEIVE_SHADOW.

If turned to FALSE, the shape / curve doesn't receive shadow.

Like all other RPR_SHAPE_VISIBILITY_* / RPR_CURVE_VISIBILITY_* flags, it will be modified when calling rprShapeSetVisibility / rprCurveSetVisibility.

* Revisiting cryptomatte.

New paramters: RPR_CONTEXT_CRYPTOMATTE_EXTENDED, PR_CONTEXT_CRYPTOMATTE_SPLIT_INDIRECT,

RPR_AOV_CRYPTOMATTE_MAT3, RPR_AOV_CRYPTOMATTE_MAT4, RPR_AOV_CRYPTOMATTE_MAT5,

RPR_AOV_CRYPTOMATTE_OBJ3, RPR_AOV_CRYPTOMATTE_OBJ4, RPR_AOV_CRYPTOMATTE_OBJ5.

RPR_CONTEXT_CRYPTOMATTE_EXTENDED : Activate the Extended mode ( default value is 0 ).

rprContextSetParameterByKey1u(ctx, RPR_CONTEXT_CRYPTOMATTE_EXTENDED, v);

If the Extended Mode is enabled, the 6 new AOV (MAT3~MAT5 and OBJ3~OBJ5) must be attached to context ( with rprContextSetAOV ).

PR_CONTEXT_CRYPTOMATTE_SPLIT_INDIRECT : If you set PR_CONTEXT_CRYPTOMATTE_SPLIT_INDIRECT = 1 with RPR_CONTEXT_CRYPTOMATTE_EXTENDED = 1

then indirect reflections/refractions of objects have different id from direct visibility.

The default value is 0.

rprContextSetParameterByKey1u(ctx, PR_CONTEXT_CRYPTOMATTE_SPLIT_INDIRECT, v);

In this header, we can find 2 versions of API:

Version 1: Working with Northstar only. Deprecated, will be replaced by version 2.

Version 2: Still under developement. The main function: rprMaterialXSetFile is implemented.

* For both MaterialX and Heterogeneous Volume, It's planned to have demos implemented in this SDK. If you need a sample urgently, feel free to contact RichardGe.

-- RPR API CHANGE:

User-Texture has been improved in Northstar: We can now define the code for CPU rendering through a callback ( instead of GPU-only before this release ), and have any textures we want ( instead of 4 limit before this release )

those 8 constants:

RPR_MATERIAL_NODE_USER_TEXTURE_0, RPR_MATERIAL_NODE_USER_TEXTURE_1, RPR_MATERIAL_NODE_USER_TEXTURE_2, RPR_MATERIAL_NODE_USER_TEXTURE_3

RPR_CONTEXT_USER_TEXTURE_0, RPR_CONTEXT_USER_TEXTURE_1, RPR_CONTEXT_USER_TEXTURE_2, RPR_CONTEXT_USER_TEXTURE_3

are now deprecated, and replaced by new API: rprContextSetUserTexture/rprContextGetUserTexture.

There is a description in the header file on how to use this new API.

For Northstar, rprShapeSetLayerMask is now deprecated. the bit-mask Render layer has been replaced by strings.

new functions:

rprShapeAttachRenderLayer/rprShapeDetachRenderLayer -> set a Render Layer on a shape. The API user can choose any name he wants.

rprContextAttachRenderLayer/rprContextDetachRenderLayer -> add/remove a Render Layer name to the final rendering.

For Northstar, add of deformation motion blur. The Demo "04_deformation_motion_blur" illustrates how to use it.

RPRNEXT-319 - Sphere Light explicit contribution is not consistent

RPRNEXT-318 - Uber metalness parameter gives an unnatural look

-- RPR API CHANGE:

RPR_AOV_MATERIAL_IDX was renamed RPR_AOV_MATERIAL_ID

this is to clarify that this AOV is rendering an ID, and not an Index.

( the ID can be changed with rprMaterialNodeSetID(rpr_material_node mat, rpr_uint id) )
