demosys.geometry¶
The geometry module is a collection of functions generating simple geometry / VAOs.
Functions¶
-
demosys.geometry.
quad_fs
() → demosys.opengl.vao.VAO¶ Creates a screen aligned quad using two triangles with normals and texture coordiantes.
Returns: A demosys.opengl.vao.VAO
instance.
-
demosys.geometry.
quad_2d
(width, height, xpos=0.0, ypos=0.0) → demosys.opengl.vao.VAO¶ Creates a 2D quad VAO using 2 triangles with normals and texture coordinates.
Parameters: - width (float) – Width of the quad
- height (float) – Height of the quad
Keyword Arguments: - xpos (float) – Center position x
- ypos (float) – Center position y
Returns: A
demosys.opengl.vao.VAO
instance.
-
demosys.geometry.
cube
(width, height, depth, center=(0.0, 0.0, 0.0), normals=True, uvs=True) → demosys.opengl.vao.VAO¶ Creates a cube VAO with normals and texture coordinates
Parameters: - width (float) – Width of the cube
- height (float) – Height of the cube
- depth (float) – Depth of the cube
Keyword Arguments: - center – center of the cube as a 3-component tuple
- normals – (bool) Include normals
- uvs – (bool) include uv coordinates
Returns: A
demosys.opengl.vao.VAO
instance
-
demosys.geometry.
bbox
(width=1.0, height=1.0, depth=1.0)¶ Generates a bounding box with (0.0, 0.0, 0.0) as the center. This is simply a box with
LINE_STRIP
as draw mode.Keyword Arguments: - width (float) – Width of the box
- height (float) – Height of the box
- depth (float) – Depth of the box
Returns: A
demosys.opengl.vao.VAO
instance
-
demosys.geometry.
plane_xz
(size=(10, 10), resolution=(10, 10)) → demosys.opengl.vao.VAO¶ Generates a plane on the xz axis of a specific size and resolution. Normals and texture coordinates are also included.
Parameters: - size – (x, y) tuple
- resolution – (x, y) tuple
Returns: A
demosys.opengl.vao.VAO
instance
-
demosys.geometry.
points_random_3d
(count, range_x=(-10.0, 10.0), range_y=(-10.0, 10.0), range_z=(-10.0, 10.0), seed=None) → demosys.opengl.vao.VAO¶ Generates random positions inside a confied box.
Parameters: count (int) – Number of points to generate
Keyword Arguments: - range_x (tuple) – min-max range for x axis: Example (-10.0. 10.0)
- range_y (tuple) – min-max range for y axis: Example (-10.0. 10.0)
- range_z (tuple) – min-max range for z axis: Example (-10.0. 10.0)
- seed (int) – The random seed
Returns: A
demosys.opengl.vao.VAO
instance
-
demosys.geometry.
sphere
(radius=0.5, sectors=32, rings=16) → demosys.opengl.vao.VAO¶ Creates a sphere.
Keyword Arguments: - radius (float) – Radius or the sphere
- rings (int) – number or horizontal rings
- sectors (int) – number of vertical segments
Returns: A
demosys.opengl.vao.VAO
instance
