## Detailed Documentation

Renderer used for rendering point clouds.

### Construction

    PointCloudRenderer()

Creates a renderer without point cloud.

    PointCloudRenderer(const cogs::PointCloud& pc)

Creates a renderer with the specified point cloud.

### Methods

    void Reset(const cogs::PointCloud& pc)

Replaces currently set point cloud with a new one.

    size_t GetPointCount() const

Returns number of points in the rendered pointcloud.

    void SetColors(const std::vector<cogs::Color3f>& colors)

Set custom color for each point.

    virtual bool IsCompatibileWithStyle(const hiro::draw::Style* style)

Test whether specified style is compatible with the object.

    virtual void OnRenderPoints()

Defines behavior on point rendering.

    virtual void OnRenderNormals()

Defines behavior on normal rendering.
