openmc.SolidRayTracePlot¶
- class openmc.SolidRayTracePlot(plot_id=None, name='')[source]¶
Phong shading-based rendering of an OpenMC geometry
This class defines a plot that uses Phong shading to enhance the visualization of an OpenMC geometry by incorporating diffuse lighting and configurable opacity for certain regions. It extends
RayTracePlotby adding parameters related to lighting and transparency.New in version 0.15.1.
- Parameters
- Variables
id (int) – Unique identifier
name (str) – Name of the plot
pixels (Iterable of int) – Number of pixels to use in each direction
filename (str) – Path to write the plot to
color_by ({'cell', 'material'}) – Indicate whether the plot should be colored by cell or by material
overlap_color (Iterable of int or str) – Color to apply to overlapping regions
colors (dict) – Dictionary indicating that certain cells/materials should be displayed with a particular color. The keys can be of type
Cell,Material, or int (ID for a cell/material).horizontal_field_of_view (float) – Field of view horizontally, in units of degrees, defaults to 70.
camera_position (tuple or list of ndarray) – Position of the camera in 3D space. Defaults to (1, 0, 0).
look_at (tuple or list of ndarray) – The center of the camera’s image points to this place in 3D space. Set to (0, 0, 0) by default.
up (tuple or list of ndarray) – Which way is up for the camera. Must not be parallel to the line between look_at and camera_position. Set to (0, 0, 1) by default.
orthographic_width (float) – If set to a nonzero value, an orthographic projection is used. All rays traced from the orthographic pixel array travel in the same direction. The width of the starting array must be specified, unlike with the default perspective projection. The height of the array is deduced from the ratio of pixel dimensions for the image. Defaults to zero, i.e. using perspective projection.
light_position (tuple or list of float) – Position of the light source in 3D space. Defaults to None, which places the light at the camera position.
diffuse_fraction (float) – Fraction of lighting that is diffuse (non-directional). Defaults to 0.1. Must be between 0 and 1.
opaque_domains (list) – List of domains (e.g., cells or materials) that should be rendered as opaque rather than allowing transparency.
