Search Results for "point"

...For this purpose the demo uses a quadtree data structure based on axis-aligned bounding boxes to speed up the search for triangles in a mesh. Depending on a search point all triangles of a quadtree's region are retrieved and relevant information about the search is shown. Quadtree creation can be parametrized by three parameters: - Maximum tree depth. - Maximum number of triangles per region. - Percentage of total number of triangles per region. The OpenGL graphics library is used to render the results, regions as well as the underlying triangle mesh. ...

This program aims to check and gain a inner point from multiple set of linear constraints. This software works better in the case that range of variables are known and parameters are configured so. C++ and Eigen library needed, and to calculate more accurate, we may need mpfr++ library or, QD library. Freezed.

...From version 2.x.x, the project will enter the stage of long-term maintenance, i.e., I probably will not add new content but only fix bugs found. If you find any bugs, please point out them in Issues, or make a Pull request to improve them, thanks!

...The trained models can be loaded onto edge devices such as IoT devices/sensors, and used to make fast and accurate predictions completely offline. A tool that adapts models trained by above algorithms to be inferred by fixed point arithmetic.

...It's distrib in 2-3 separate modules: 1. the C++ implementation of the terrain- and/or surface- rendering Algorithms I have developed: both a multithread and a non-multithread variant is relaeased. 2. Seme as at point 1. , but with a road-network rendering and collision-detection module I wrote before. It also adds some trees at the top of the terrain. (multitread vesion not released yet) 3. Seme as point 2.. Multithread terrain-rendering, roads on it, and vehicles to go around. The most important part is terrain-rendering. The Algorithm at the heart of it features my first and second theorem abut polygonal surface approximation. ...

psimpl - generic n-dimensional polyline simplification. psimpl is a lightweight C++ library that is generic, easy to use, and supports multiple simplification algorithms, including Douglas-Peucker.

This library is being created as I have a need to do very fast FFTs on low end devices not supporting the NEON instruction set. The Raspberry Pi is an ideal candidate for developing in gcc before porting to JNI for low spec Android devices, hence it's inclusion. Fixed point 16/32 integer FFT library suitable for the Raspberry Pi and Android devices. Includes test stubs for gcc on the Raspberry Pi and a Basic4Android wrapper from JNI. It includes hand optimised ARMv6 assembler, demonstrating techniques such as pipeline stuffing to achieve maximum performance. It also demonstrates how to include large chunks of assembler inline with C/C++ thus avoiding ABI issues between platforms.

A bignum library written in the C++ programming language as templates. It provides standard mathematical operations like add, sub, mul, div, pow etc. with the big integer and big floating point numbers.

A random collection of c++ tidbits. I write some code as I go along. Maybe this is useful to anyone. Maybe I will turn some of it into a library at some point. But not now.

This projects hosts the worlds fastest algorithms for the labeling of point-features. It especially looks for algorithms thar are free of constraints, applicable to many scenarios (e.g., visualization, maps...) and do not need any preprocessing.

a simple software implemented FPU. only 32bit precision is supported and the operation result is not accurate as modern FPUs, but it is light and compact. (uses simple 32bit integer operations only, good for machines that has no hardware FPU.)

A library that does preform precise floating point operations designed for industrial / banking solutions.

This is module for basic computation with floating point numbers. Numbers can have very wide mantissa for good precision, for realize "arbitrary-precision arithmetic". Module was adapt for BCB and MSVC compilers. Russian comments.

Let P be a 2D point expressed in a plane area defined by four 2D points A,B,C,D. The aim of our C++ class is to express the coordinates of P in order to match when A,B,C,D is rectified as a rectangle. A demo application shows the use of the C++ class.

Implementation of an Interval Iterative Closest Point that uses intervals to found the global optimal solution. ICP can be used in vision technologies and photogrametry as pattern mathcing and as geometrical model finder.

It software decodes EAN-13 bar code picture by image processing. And a GUI is ship together with it, which can take picture from web camera. So the only thing you need to recognise barcode apart you computer is a webcam.
