Struct cogl::GLES2Context [−][src]
Implementations
impl GLES2Context
[src]
pub fn new(ctx: &Context) -> Result<GLES2Context, Error>
[src]
Allocates a new OpenGLES 2.0 context that can be used to render to
CoglOffscreen
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 cogl_push_gles2_context
. For those familiar with
using the EGL api, this serves a similar purpose to eglMakeCurrent.
<note>
Before using this api applications can check for OpenGLES 2.0
api support by checking for FeatureID::OglFeatureIdGles2Context
support
with cogl_has_feature
. This function will return false
and
return an GLES2ContextError::Unsupported
error if the
feature isn’t available.</note>
ctx
A Context
Returns
A newly allocated GLES2Context
or None
if there
was an error and error
will be updated in that case.
