pub struct GLES2Context {}

Implementations

impl GLES2Context

pub fn new(ctx: &Context) -> GLES2Context

Allocates a new OpenGLES 2.0 context that can be used to render to Offscreen framebuffers (Rendering to Onscreen framebuffers is not currently supported).

To actually access the OpenGLES 2.0 api itself you need to use GLES2Context::get_vtable. You should not try to directly link to and use the symbols provided by the a system OpenGLES 2.0 driver.

Once you have allocated an OpenGLES 2.0 context you can make it current using push_gles2_context. For those familiar with using the EGL api, this serves a similar purpose to eglMakeCurrent.

Before using this api applications can check for OpenGLES 2.0 api support by checking for FeatureID::OglFeatureIdGles2Context support with has_feature. This fn will return false and return an GLES2ContextError::Unsupported error if the feature isn’t available.

`ctx`

A Context

Returns

A newly allocated GLES2Context or None if there was an error and error will be updated in that case.
