Questions tagged [vertices]

A vertex (plural: vertices) has a slightly different meaning depending on context. Computer graphics - data structure that describes position of a point in 2D or 3D space. Geometry - point where higher-dimensional geometric objects meet; Graph theory - fundamental unit of graphs;

A vertex in computer graphics is a data structure that describes certain attributes, like the position of a point in 2-Dimensional or 3-Dimensional space, at multiple points on a surface.

In geometry, a vertex is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

In mathematics, and more specifically in graph theory, a vertex or node is the fundamental unit of which graphs are formed (usually represented by a circle with a label)

Vertices not merged (output from Kinect Fusion)

I have a major problem right now. I was using the kinect fusion to capture a 3D scene and output it as an .OBJ file. The output of the file looks something like this: v 123 123 123 v 123 123 123 v 123 123 123 vn 321 321 321 vn 321 321 321 vn 321 321…

XNA Vertices don't appear when the camera is at 0,0,0

I have, what I think is going to be a very obvious question to some so I'm hoping someone could quickly clean it up for me. I have an XNA app where I draw a grid of vertices and the camera is positioned 20.0f above it. If I place the camera at 0,…

Box2D Vertices in Shapes

I have a polygon shape in Box2D. The shape is a Triangle, wich I expect to have 3 vertices. In fact all shapes that I create will output 8 vertices. Why is this? And if I output the vertex count, that is always the correct amount. I dont want to…

Planewidth after bending (using pv3d, as3dmod)

I got a huge problem. I'm stuck there for two weeks now. It's seems pretty simple. I'm creating a plane, mapping a texture to it. After that I bend it, using the bend modifier from as3dmod. Of course the plane got smaller after the bending…

Most basic transformed vertex-drawing with Direct3D

I'm absolutely new to DirectX and I'd like to draw some untransformed primitives with the most basic Direct3D configuration (for learning purposes). I already drew some primitives with transformed vertices, that is vertices with the D3DFVF_XYZRHW…
