Constructor & Destructor Documentation

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.__init__	(		self,
			jsondict
	)

Member Function Documentation

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.idx_buffer	(		self,
			idx_buffer,
			num_vtx,
			start_idx,
			inst_idx
	)

Fill the provided index buffer to draw the shape.

Args:
- idx_buffer (omr.MIndexBuffer): un-allocated storage for our result.
- num_vtx (int): The total number of vertices in the VBO.
- startIdx (int): the index of our first vtx in the VBO
- item_idx (int): 0 = outer frustum, 1 = inner frustum, 2 = frustum edges

Here is the call graph for this function:

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.instance_enabled	(		self,
			instance_idx
	)

Return the enable state of the instance/MRenderItem, potentially taking
named params into account.

Check the position of the light in Z to decide if it should draw.

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.is_static

(

self

)

Tells the vp code if the geometry is static or deforming, like a spot
light frustum for example

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.num_lights

(

self

)

Here is the caller graph for this function:

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.opacity

(

self

)

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.ordered_proj_vectors	(		self,
			light_idx
	)

Generator to get the vectors from one corner of a light filter to
another corner of the light.

Here is the caller graph for this function:

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.set_connected_lights_data	(		self,
			this_obj
	)

Get data from connected lights to be able to draw the frustum.

- For each connected light
  - compute its matrix in filter-space
  - compute the position of the light's corners in filter-space and store
    them for later use.

Args:
- this_obj (om.MObject): The maya object

Here is the caller graph for this function:

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.set_input_params	(		self,
			obj,
			kwargs
	)

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.validate (   subdivs )

static

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.vtx_buffer

(

self

)

Return a list of vertices (list) in local space.

Use the vtx_list (the original light shape) to build the outer coneAngle
at the specified depth.

Here is the call graph for this function:

def rfm2.vp.geo.projective_frustum.ProjectiveFrustum.vtx_buffer_count

(

self

)

Return the number of vertices in this buffer.
