Project 3D
Project a 3D body after rotation and translation
PROJ3D(aglyph, M = diag(1, nrow = 4), M2 = diag(1, nrow = 4),
anorms = list(), zee = c(0, 0, 1))aglyph |
glyph structure |
M |
rotation matrix |
M2 |
rotation matrix |
anorms |
normals to structure |
zee |
Up direction of body |
This function takes a 3D body, rotates it and projects it for plotting. An example glyph is found in Z3Darrow.
Glyph structure
x,y,z |
coordinates of rotated body faces |
xp |
rotated normal vectors |
zd |
depth mean value of each face |
