Detailed Description

A QGeometryRenderer holds all the information necessary to draw a QGeometry . A QGeometry holds the coordinates of the geometry data - QGeometryRenderer specifies how to interpret that data.

class PrimitiveType

The type of the primitive.

Qt3DRender.QGeometryRenderer.Points	List of points
Qt3DRender.QGeometryRenderer.Lines	List of lines
Qt3DRender.QGeometryRenderer.LineLoop	Connected group of lines connected at ends forming a loop
Qt3DRender.QGeometryRenderer.LineStrip	Connected group of lines
Qt3DRender.QGeometryRenderer.Triangles	List of triangles
Qt3DRender.QGeometryRenderer.TriangleStrip	List of connected triangles
Qt3DRender.QGeometryRenderer.TriangleFan	List of connected triagles where all triangles share the first vertex
Qt3DRender.QGeometryRenderer.LinesAdjacency	Allows geometry shader to access adjacent lines in a line list

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property firstInstanceᅟ: int

Holds the base instance.

Access functions:

• firstInstance()

• setFirstInstance()

• Signal firstInstanceChanged()

property firstVertexᅟ: int

Holds the base vertex.

Access functions:

• firstVertex()

• setFirstVertex()

• Signal firstVertexChanged()

property geometryᅟ: QGeometry

Holds the geometry.

Access functions:

• geometry()

• setGeometry()

• Signal geometryChanged()

property indexBufferByteOffsetᅟ: int

Holds the byte offset into the index buffer.

Access functions:

• indexBufferByteOffset()

• setIndexBufferByteOffset()

• Signal indexBufferByteOffsetChanged()

property indexOffsetᅟ: int

Holds the base vertex.

property instanceCountᅟ: int

property primitiveRestartEnabledᅟ: bool

Holds the primitive restart flag.

property primitiveTypeᅟ: Qt3DRender.QGeometryRenderer.PrimitiveType

Holds the primitive type.

Access functions:

• primitiveType()

• setPrimitiveType()

• Signal primitiveTypeChanged()

property restartIndexValueᅟ: int

Holds the restart index.

Access functions:

• restartIndexValue()

• setRestartIndexValue()

• Signal restartIndexValueChanged()

property sortIndexᅟ: float

Overrides the sorting index when depth sorting is enabled.

If depth sorting is enabled on the frame graph, the renderer will sort objects based on how far the center of the bounding volume is from the camera and render objects from the furthest to the closest.

This property can be used to override the depth index and precisely control the order in which objects are rendered. This is useful when all objects are at the same physical distance from the camera.

The actual values are not significant, only that they define an order to sort the objects. These are sorted such as the object with the smallest value is drawn first, then the second smallest, and so on.

Note

Setting this to -1.f will disable the explicit sorting for this entity and revert to using the distance from the center of the bounding volume.
