Ton Roosendaal (Dutch: [tɔn ˈroːzə(n)ˌdaːl]; born 20 March 1960 [1]) is a Dutch software developer and film producer.He is the original creator of the open-source 3D creation suite Blender and Traces [2] (an Amiga ray tracer which was the forerunner of Blender).
Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, macOS, BSD, Haiku, IRIX and Linux. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating video games.
Blender Game Engine was developed in 2000 with the goal of creating a marketable commercial product to create games and other interactive content, in an artist-friendly way. Key code in the physics library (SUMO) did not become open-source when the rest of Blender did, which prevented the game engine from functioning until version 2.37a.
A procedural program is composed of one or more units or modules, either user coded or provided in a code library; each module is composed of one or more procedures, also called a function, routine, subroutine, or method, depending on the language. Examples of procedural languages include:
A reflection about a line or plane that does not go through the origin is not a linear transformation — it is an affine transformation — as a 4×4 affine transformation matrix, it can be expressed as follows (assuming the normal is a unit vector): [′ ′ ′] = [] [] where = for some point on the plane, or equivalently, + + + =.
Complete Java code for a 1-D and 2-D DWT using Haar, Daubechies, Coiflet, and Legendre wavelets is available from the open source project: JWave. Furthermore, a fast lifting implementation of the discrete biorthogonal CDF 9/7 wavelet transform in C, used in the JPEG 2000 image compression standard can be found here (archived 5 March 2012).
Hadamard transform (or, Walsh–Hadamard transform) Fast wavelet transform; Hankel transform, the determinant of the Hankel matrix; Discrete Chebyshev transform. Equivalent, up to a diagonal scaling, to a discrete cosine transform; Finite Legendre transform; Spherical Harmonic transform; Irrational base discrete weighted transform; Number ...
Trilinear interpolation is a method of multivariate interpolation on a 3-dimensional regular grid. It approximates the value of a function at an intermediate point ( x , y , z ) {\displaystyle (x,y,z)} within the local axial rectangular prism linearly, using function data on the lattice points.
