Sort by:

List of functions:

Controls visualizer-related settings. The visualizer is used to render mesh wireframe, object bounding boxes, and all sorts of visual helpers (such as physical collision shapes, joints, etc.).

Usage Example

To render a world origin, do the following:

Source code (C++)

// AppWorldLogic.cpp
#include "AppWorldLogic.h"
#include "UnigineVisualizer.h"

using namespace Unigine;
using namespace Math;

int AppWorldLogic::init() {
	/* ... */
	// enable the visualizer
	Visualizer::get()->setEnabled(1);

	return 1;
}

int AppWorldLogic::update() {
	// render world origin
	Visualizer::get()->renderVector(Vec3(0.0f,0.0f,0.1f), Vec3(1.0f,0.0f,0.1f), vec4(1.0f,0.0f,0.0f,1.0f));
	Visualizer::get()->renderVector(Vec3(0.0f,0.0f,0.1f), Vec3(0.0f,1.0f,0.1f), vec4(0.0f,1.0f,0.0f,1.0f));
	Visualizer::get()->renderVector(Vec3(0.0f,0.0f,0.1f), Vec3(0.0f,0.0f,1.1f), vec4(0.0f,0.0f,1.0f,1.0f));
