PhysIKA: Physics-based Interactive Kinematics Architecture

master: dev:

Introduction

PhysIKA is an open source node-based architecture targeted at real-time simulation of versatile physical materials. Currently, it supports simulating physical phenomena ranging from fluids, elastic objects and fracture, etc. It is higly modualized and can also help the research community develop more novel algorithms.

Getting Started

The following instructions will guide you to set up an simple elastic object.

Prerequisites

• CUDA 9.0 +
• CMake 3.12 +

Installing

• Download the source code;
• Run cmake and set up both "Where is the source code" and "Where to build the binaries";
• Click Configure;
• If succeeded, then click Generate.

Runing an example

The following example shows how to create an elastic bunny within less than 30 lines of codes.

#include <iostream>
#include "GUI/GlutGUI/GLApp.h"
#include "Framework/Framework/SceneGraph.h"
#include "Dynamics/ParticleSystem/ParticleElasticBody.h"
#include "Dynamics/ParticleSystem/StaticBoundary.h"

using namespace Physika;

int main()
{
	SceneGraph& scene = SceneGraph::getInstance();

	std::shared_ptr<StaticBoundary<DataType3f>> root = scene.createNewScene<StaticBoundary<DataType3f>>();
	root->loadCube(Vector3f(0), Vector3f(1), true);

	std::shared_ptr<ParticleElasticBody<DataType3f>> bunny = std::make_shared<ParticleElasticBody<DataType3f>>();
	root->addParticleSystem(bunny);
	bunny->getRenderModule()->setColor(Vector3f(0, 1, 1));
	bunny->setMass(1.0);
	bunny->loadParticles("../Media/bunny/bunny_points.obj");
	bunny->loadSurface("../Media/bunny/bunny_mesh.obj");
	bunny->translate(Vector3f(0.5, 0.2, 0.5));
	bunny->setVisible(false);

	GLApp window;
	window.createWindow(1024, 768);

	window.mainLoop();

	return 0;
}
