This function transforms a point from one space to another.

Syntax

• static Vec3 Point(const Vec3& point, Entity* src, Entity* dst)
• static Vec3 Point(float x, float y, float z, Entity* src, Entity* dst)
• static Vec3 Point(const Vec3& point, const Mat4& src, const Mat4& dst)
• static Vec3 Point(float x, float y, float z, const Mat4& src, const Mat4& dst)

Parameters

• point: the point to be transformed.
• x: the X component of the point to be transformed.
• y: the Y component of the point to be transformed.
• z: the Z component of the point to be transformed.
• src: the source entity or 4x4 matrix to transform the point from.
• dst: the destination entity or 4x4 matrix to transform the point to.

Returns

Returns the transformed point.

Example

#include "Leadwerks.h"



using namespace Leadwerks;



Model* model = NULL;



int main(int argc, const char *argv[])

{

        Leadwerks::Window* window = Leadwerks::Window::Create();

        World* world = World::Create();

        Camera* camera = Camera::Create();

        camera->Move(0,0,-3);

        Light* light = DirectionalLight::Create();

        light->SetRotation(35,35,0);

        

        //Create a model

        model = Model::Box();

        model->SetColor(0.0,0.0,1.0);

        model->SetPosition(3,0,0);



        while (true)

                if (window->KeyHit(Key::Escape) || window->Closed()) return false;



                Leadwerks::Time::Update();

                world->Update();

                world->Render();

                        

                //We're going to transform the position (2,0,0) from global space to the model's local space

                //Because the model is positioned at (3,0,0) the point will be at (-1,0,0) in local space (relative to the model).

                Vec3 position = Transform::Point(2,0,0,NULL,model);



                context->SetBlendMode(Blend::Alpha);

                context->DrawText(position.ToString(),2,2);

                context->SetBlendMode(Blend::Solid);



                context->Sync(false);
