GLMeshItem

class pyqtgraph.opengl.GLMeshItem(**kwds)

Bases: GLGraphicsItem

Displays a 3D triangle mesh.

__init__(**kwds)

Arguments:
meshdata	MeshData object from which to determine geometry for this item.
color	Default face color used if no vertex or face colors are specified.
edgeColor	Default edge color to use if no edge colors are specified in the mesh data.
drawEdges	If True, a wireframe mesh will be drawn. (default=False)
drawFaces	If True, mesh faces are drawn. (default=True)
shader	Name of shader program to use when drawing faces. (None for no shader)
smooth	If True, normal vectors are computed for each vertex and interpolated within each face.
computeNormals	If False, then computation of normal vectors is disabled. This can provide a performance boost for meshes that do not make use of normals.

meshDataChanged()

This method must be called to inform the item that the MeshData object has been altered.

setColor(c)

Set the default color to use when no vertex or face colors are specified.

setMeshData(**kwds)

Set mesh data for this item. This can be invoked two ways:

1. Specify meshdata argument with a new MeshData object
2. Specify keyword arguments to be passed to MeshData(..) to create a new instance.

setShader(shader)

Set the shader used when rendering faces in the mesh. (see the GL shaders example)
