I am trying to use the geometry data type and was wondering what the unit of the spatial functions will be. The documentation says as below. Is there ...

I want to preface this post: This is perhaps more of a math question than a coding question. I am developing a plant (lettuce) model which involves s ...

I am having trouble with finding the X and Y-coordinates of the center of a rotated rectangle through mathematical calculations. What I have is the wi ...

Hi, I am in need of estimating the distance between the two opposite sides of a quadrilateral as shown in the image. I know the coordinates of P_0, ...

I found this great question with some concise code that, with a couple of tweaks, fits a 3D polynomial surface onto a set of points of in space. Pyth ...

I am trying to save patches from OpenSubdiv subdivision using Open Cascade for one of my app that I am trying to build for subdivision surfaces. This ...

I'm trying to plot a 3D pyramid frustum (surface plot) in a python program, where the frustum geometry is given by the plane images below: Where al ...

Given a list of n circles, each of diameter d, I want to generate an n-gon (polygon of n lengths), with side lengths d, and draw a circle on each o ...

I have an optimization problem that I can't seem to wrap my head around. I have two shapes, both of which are described by parametric equations. Call ...

Assume a Rope of a given length and a given stiffness (that means a minimum bending radius). Both ends are fixed at a given point in a given direction ...

I was doing image processing to determine the distance between two points in a picture. it involves a fair amount of geometry. One of the problems whi ...

I have 3 rows data used as X,Z, Y separately. But Z data is directly read from a csv file, so it's not a function of (x,y). The data shows: I refe ...

My goal is to calculate the area of the complete figure in the coordinate plane, excluding the intersecting area. Can someone help me see what I need ...

I have the segmentation results from one algorithm, however, the generated triangle surface is not manifold geometry. I am asking this question here i ...

I'm trying to determine if an infinite cylinder and circle intersect in 3D space. This has been asked here: Finding the intersection of the Circle and ...

I have uploaded the Local Government Area Boundary of the NSW, Australia into my MS-SQL database and try to filter for Sydney Area. Following is the ...

While working on a simple Radar simulator, I wish to be able to stream (x,y) coordinates of objects position. Generating object positions moving in ra ...

I have a triangular mesh of the brain surface. I want to remesh it to a high-quality Delaunay triangulation. I'm seeking an easy and straightforward m ...

I want to make the face of half a cylinder, using the boundary edges (two vertical lines and two 180° arcs). I know there are easier ways to do this, ...

I have in mind this video, or this simulation, and I would like to reproduce the geodesic lines on some sort of surface in 3D, given by a function f(x ...
