tfg.rendering.opengl.math.model_to_screen

Transforms points from model to screen coordinates.

tfg.rendering.opengl.math.model_to_screen(
    point_model_space, model_to_eye_matrix, perspective_matrix, screen_dimensions,
    lower_left_corner=(0.0, 0.0), name=None
)

Note:

Please refer to http://www.songho.ca/opengl/gl_transform.html for an in-depth review of this pipeline.

Note:

In the following, A1 to An are optional batch dimensions which must be broadcast compatible.

point_model_space A tensor of shape [A1, ..., An, 3], where the last dimension represents the 3D points in model space.
model_to_eye_matrix A tensor of shape [A1, ..., An, 4, 4], where the last two dimension represent matrices to transform points from model to eye coordinates.
perspective_matrix A tensor of shape [A1, ..., An, 4, 4], where the last two dimension represent matrices to transform points from eye to clip coordinates.
screen_dimensions A tensor of shape [A1, ..., An, 2], where the last dimension is expressed in pixels and captures the width and the height (in pixels) of the screen.
lower_left_corner A tensor of shape [A1, ..., An, 2], where the last dimension captures the position (in pixels) of the lower left corner of the screen.
name A name for this op. Defaults to 'model_to_screen'.

InvalidArgumentError if any input contains data not in the specified range of valid values.
ValueError If any input is of an unsupported shape.

A tuple of two tensors, respectively of shape [A1, ..., An, 3] and [A1, ..., An, 1], where the first tensor containing the projection of point_model_space in screen coordinates, and the second represents the 'w' component of point_model_space in clip space.
