NextParticle()

Advances the pointer to the next particle in the buffer, so that its first vertex can be written

public void NextParticle()

NextSegment()

Advances the pointer to the next segment in the buffer, so that its first vertex can be written

public void NextSegment()

NextVertex()

Advances the pointer to the next vertex in the buffer, so that it can be written

public void NextVertex()

SetAttribute(AttributeAccessor, nint)

Sets the data for the current vertex using the provided AttributeAccessor

public void SetAttribute(AttributeAccessor accessor, nint ptrRef)

Parameters

accessor AttributeAccessor

Accessor to the vertex data

ptrRef nint

Pointer to the source data

SetAttributePerParticle(AttributeAccessor, nint)

Sets the same data for the all vertices in the current particle using the provided AttributeAccessor

public void SetAttributePerParticle(AttributeAccessor accessor, nint ptrRef)

Parameters

accessor AttributeAccessor

Accessor to the vertex data

ptrRef nint

Pointer to the source data

SetAttributePerSegment(AttributeAccessor, nint)

Sets the same data for the all vertices in the current particle using the provided AttributeAccessor

public void SetAttributePerSegment(AttributeAccessor accessor, nint ptrRef)

Parameters

accessor AttributeAccessor

Accessor to the vertex data

ptrRef nint

Pointer to the source data

SetVerticesPerSegment(int, int, int)

Sets how many vertices are associated with the first, middle and last quad segments of the buffer. In case of billboards 1 segment = 1 quad but other shapes might be laid out differently

public void SetVerticesPerSegment(int verticesForFirstSegment, int verticesForMiddleSegment, int verticesForLastSegment)

Parameters

verticesForFirstSegment int

Number of vertices for the first segment

verticesForMiddleSegment int

Number of vertices for the middle segments

verticesForLastSegment int

Number of vertices for the last segment

StartOver()

Moves the index to the beginning of the buffer so that the data can be filled from the first particle again

public void StartOver()
