Algorithm (Workflow)
This algorithm generates a 2.5D solid geometry of a bolt using a vertex list (VL) and a facet list (FL). The function is designed to create a cylindrical shape based on the given parameters.
Input Parameters
- R: Outer Radius of the bolt. It defines the size of the bolt's circular base.
- H: Height of the bolt. It determines the vertical dimension of the bolt.
Output Results
- VL: Vertex list. It contains the coordinates of the vertices that define the shape of the bolt.
- FL: Facet list. It describes the triangular facets that make up the surface of the bolt.
Algorithm Steps
- Set
n to 16, which is the number of segments used to approximate the circular base of the bolt.
- Calculate
dw as 2*pi/n, which is the angular increment for each segment.
- Initialize
w to -dw/2 to start the angle from the midpoint of the first segment.
- Create a zero matrix
PL with dimensions n x 2 to store the 2D coordinates of the circle's vertices.
- Iterate over each segment from 1 to
n:
- Increment
w by dw.
- Calculate the x and y coordinates using
cos(w)*R and sin(w)*R, respectively.
- Store the coordinates in the
PL matrix.
- Call the function
VLFLofPLz(PL,H) to generate the vertex and facet lists based on the 2D profile PL and height H.
- Return the vertex list
VL and facet list FL.
