Struct rovr::render::RenderContext [-] [+] [src]

pub struct RenderContext<'a> {
    // some fields omitted
}

An active Oculus rendering context associated with an HMD. Only OpenGL is supported. This provides access to the basic metadata necessary to prepare OpenGL framebuffers for drawing.

See hmd.render_to() for details on use.

Methods

`impl<'a> RenderContext<'a>`

`fn dismiss_hsw(&self)`

Dismiss the Health and Safety warning automatically displayed by the Oculus runtime. This should only be dismissed in response to user input; see the Oculus SDK documentation for details on proper usage.

`fn recenter_pose(&self)`

Recenter the headset, using the current orientation and position as the origin.

`fn target_texture_size(&self, eye: &Eye) -> (u32, u32)`

Return a (width, height) tuple containing the suggested size for a render target for the given eye.

`fn projection_matrix(&self, eye: &Eye, near_z: f32, far_z: f32) -> Matrix4`

Create an appropriate projection matrix for the given eye. This will properly account for the native field of view of the associated headset. The returned matrix is a right-handed projection with an OpenGL clipping range (-w to w).

`fn create_binding(&self, tex_id_left: u32, tex_id_right: u32) -> TextureBinding`

Create a texture binding given a pair of OpenGL texture IDs for the left and right eye, respectively. The left and right textures should be of the size suggested by target_texture_size.

Trait Implementations

`impl<'a> CreateRenderContext<'a> for RenderContext<'a>`

`fn new(owning_hmd: &'a Hmd, target: &'a RenderTarget) -> Result<RenderContext<'a>, OculusError>`

Create an active Oculus rendering context.
