maskBuffer

public MTLBuffer maskBuffer()

Mask buffer containing one uint32_t mask per polygon. May be nil. Otherwise, the mask type must be specified on the MPSRayIntersector with which it is used.

This is an alias for polygonBuffers[0].maskBuffer. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

new_objc

public static MPSPolygonAccelerationStructure new_objc()

polygonBuffers

public NSArray<? extends MPSPolygonBuffer> polygonBuffers()

Array of polygon buffers. Each buffer contains a vertex buffer and optional index and mask buffer for an array of polygons. Changing the length of this array requires rebuilding the acceleration structure.

Using more than one MPSPolygonBuffer will reduce performance. It is better to concatenate these buffers into a single vertex buffer, index buffer, and mask buffer and use a single MPSPolygonBuffer if possible. This also applies when using an MPSInstanceAccelerationStructure: each instance or subclass of MPSPolygonAccelerationStructure in an instance hierarchy should use the same vertex buffer, index buffer, and mask buffer, although each acceleration structure may use different offsets into these buffers. This allows for the vertex, index, and mask buffers to be bound directly instead of indirectly through an argument buffer.

There must be at least one MPSPolygonBuffer. On argument buffer tier 1 devices, there must be be exactly one MPSPolygonBuffer. Use the argumentBuffersSupport property of the MTLDevice to check for support.

polygonCount

public long polygonCount()

Number of polygons. Changes to this property require rebuilding the acceleration structure.

This is an alias for polygonBuffers[0].polygonCount. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

public static boolean resolveInstanceMethod(org.moe.natj.objc.SEL sel)

setIndexBuffer

public void setIndexBuffer(MTLBuffer value)

Index buffer containing index data. Each index references a vertex in the vertex buffer. May be nil.

This is an alias for polygonBuffers[0].indexBuffer. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

setIndexBufferOffset

public void setIndexBufferOffset(long value)

Offset, in bytes, into the index buffer. Defaults to 0 bytes. Must be aligned to a multiple of the index type. Changes to this property require rebuilding the acceleration structure.

public void setIndexType(int value)

Index type. Defaults to MPSDataTypeUInt32. Only MPSDataTypeUInt16 and MPSDataTypeUInt32 are supported.

public void setMaskBuffer(MTLBuffer value)

Mask buffer containing one uint32_t mask per polygon. May be nil. Otherwise, the mask type must be specified on the MPSRayIntersector with which it is used.

This is an alias for polygonBuffers[0].maskBuffer. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

This is an alias for polygonBuffers[0].maskBufferOffset. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

setPolygonBuffers

public void setPolygonBuffers(NSArray<? extends MPSPolygonBuffer> value)

Array of polygon buffers. Each buffer contains a vertex buffer and optional index and mask buffer for an array of polygons. Changing the length of this array requires rebuilding the acceleration structure.

Using more than one MPSPolygonBuffer will reduce performance. It is better to concatenate these buffers into a single vertex buffer, index buffer, and mask buffer and use a single MPSPolygonBuffer if possible. This also applies when using an MPSInstanceAccelerationStructure: each instance or subclass of MPSPolygonAccelerationStructure in an instance hierarchy should use the same vertex buffer, index buffer, and mask buffer, although each acceleration structure may use different offsets into these buffers.

setPolygonType

public void setPolygonType(long value)

The type of polygon. Defaults to MPSPolygonTypeTriangle. Changes to this property require rebuilding the acceleration structure.

setVersion_static

public static void setVersion_static(long aVersion)

setVertexBuffer

public void setVertexBuffer(MTLBuffer value)

Vertex buffer containing vertex data encoded as three 32 bit floats per vertex. Note that by default each vertex is aligned to the alignment of the vector_float3 type: 16 bytes. This can be changed using the vertexStride property. A vertex buffer must be provided before the acceleration structure is built.

When using triangle polygons, degenerate (zero or negative area) triangles are ignored during acceleration structure construction. This can be used to pad triangle indices if needed.

Quadrilateral polygons are internally treated as two triangles. If the quadrilateral has vertices v0, v1, v2, and v3, the two triangles will have vertices v0, v1, v2 and v0, v2, v3. A quadrilateral may be used to represent a triangle by repeating the last vertex. If the first triangle is degenerate (zero or negative area), the entire quadrilateral will be ignored. This can be used to pad quadrilateral indices if needed. All four vertices of a quadrilateral must be coplanar and the quadrilateral must be convex.

This is an alias for polygonBuffers[0].vertexBuffer. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

setVertexBufferOffset

public void setVertexBufferOffset(long value)

Offset, in bytes, into the vertex buffer. Defaults to 0 bytes. Must be aligned to 4 bytes.

This is an alias for polygonBuffers[0].vertexBufferOffset. There must be exactly one polygon buffer to use this property, or the polygonBuffers property must be nil, in which case an MPSPolygonBuffer will be created automatically.

setVertexStride

public void setVertexStride(long value)

Offset, in bytes, between consecutive vertices in the vertex buffer. Defaults to 0 bytes, indicating that the vertices are packed according to the natural alignment of the vector_float3 type: 16 bytes.

This can be used to skip past any additional per-vertex data which may be stored alongside the position such as the vertex normal and texture coordinates. Must be a multiple of 4 bytes, and must be at least 12 bytes. Changes to this property require rebuilding the acceleration structure.
