Member Function Documentation

get_bloom_texture()

std::shared_ptr<gl::texture_2d> render::bloom_pass::get_bloom_texture ( ) const

inline

Returns the texture containing the bloom result.

Definition at line 92 of file bloom-pass.hpp.

render()

void render::bloom_pass::render ( render::context &  ctx )

overridevirtual

Renders a bloom texture.

Parameters

ctx	Render context.
queue	Render queue.

Implements render::pass.

Definition at line 73 of file bloom-pass.cpp.

resize()

void render::bloom_pass::resize

(

)

Resizes the mip chain resolution according to the resolution of the source texture.

set_filter_radius()

void render::bloom_pass::set_filter_radius

(

float

radius

)

Sets the upsample filter radius.
