Joining and Separating Objects in Blender - dummies

In the course of creating models for your scenes in Blender, you may need to treat separate objects as a single one, or break the parts of a single object into their own distinct objects — for example, you may accidentally add a new primitive while you're still in Edit mode. Of course, you can [.]

IfcCsgSolid - Lawrence Berkeley National Laboratory

IfcCsgSolid. Definition from ISO/CD 10303-42:1992: A solid represented as a CSG model is defined by a collection of so-called primitive solids, combined using regularized Boolean operations.The allowed operations are intersection, union, and difference. As a special case a CSG solid can also consists of a single CSG primitive.

Add procedural geometry samples by Epihaius · Pull Request .

This is a collection of several samples, combined with a simple sizer-based custom GUI system, based on the creation of 3D model primitives. The samples range from very basic to quite advanced, with a couple of demo's intended for pure entertainment thrown in. Apart from a simple cube, five standard 3D model primitive types can be generated with the code provided in the src/prim package: box .

Unity - Manual: Primitive and placeholder objects

Unity can work with 3D models of any shape that can be created with modeling software. However, there are also a number of primitive object types that can be created directly within Unity, namely the Cube, Sphere, Capsule, Cylinder, Plane and Quad.These objects are often useful in their own right (a plane is commonly used as a flat ground surface, for example) but .

Performance of GLSL geometry shaders unexpectedly slow

I'm trying to learn how to program GLSL Geometry shaders. My test project works like this: I have N VBO's which are modeling "blades of grass". Without the shader, each blade of grass is just basically a line strip with 20 segments. I was able to get this animating more or less smoothly with almost N=10k blades so that's 200,000 lines.

Geometric Primitives - Documentation

All geometric primitives normally inherit their color and opacity from the graphics state. However, explicit colors and opacities can be provided when defining the primitive ("Cs" and Os"). Associated with each geometric primitive definition are additional primitive variables that are passed to their shaders.

Geometry reference - PUC-Rio

The fundamental issue is that the Primitive class defines a "has-a" relationship for its geometry. That is, a single Primitive is defined such that it is a container for its geometric parts. For example, Box has six geometric parts: FRONT, BACK, LEFT, RIGHT; TOP, and; BOTTOM. To facilitate this relationship the Primitive class is derived .

Geometric Tools | Names and Uses in Euclidean Geometry

Geometric tools are the instruments used to draw different types of geometric shapes. In Maths, geometry is the most crucial topic, where we learn about shapes of objects. To draw these shapes there are different types of tools with different names used while solving problems based on geometry.

Blades: a new class of geometric primitives for feeding 3D .

The vibratory bowl feeder remains the most common approach to the automated feeding (orienting) of industrial parts. We study the algorithmic design of devices on the bowl feeder track that filter out all but one orientation of a given polyhedral part. In this context, we propose a simple new primitive, consisting of one horizontally mounted convex polygonal metal "blade", that can feed a .

We also have a new class Employee that looks identical to Animal in terms of shape. We create some instances of these classes and then try to assign them to each other to see what will happen. Because Animal and Rhino share the private side of their shape from the same declaration of private name: string in Animal, they are compatible.

Dynamically find the class that represents a primitive .

The Class instances for the primitive types are obtainable as you said using e.g. int.class, but it is also possible to get the same values using something like Integer.TYPE.Each primitive wrapper class contains a static field, TYPE, which has the corresponding primitive class instance. You cannot obtain the primitive class via forName, but you can get it from a class which is readily available.
