base¶

警告

这部分内容涉及 JAnim 实现原理，可能较为复杂，若没有研究源码的需求，你应酌情阅读

class janim.render.base.Programs(cache: 'dict[Any, mgl.Program | mgl.ComputeShader]' = <factory>, additional: 'list[mgl.Program]' = <factory>)¶

基类：object

cache: dict[Any, Program | ComputeShader]¶

additional: list[Program]¶

janim.render.base.get_programs(ctx: Context)¶

class janim.render.base.Renderer¶

基类：object

渲染器的基类

重写 render() 以实现具体功能

data_ctx: ContextVar = <ContextVar name='Renderer.data_ctx'>¶

render(item) → None¶

static get_u_fix_in_frame(prog: Program) → Uniform¶

static update_fix_in_frame(uniform: mgl.Uniform, item: Item) → None¶

static update_dynamic_buffer_data(new_data: ~numpy.ndarray, vbo: ~moderngl.Buffer, resize_target: int, use_32bit_align: bool = False, assert_dtype: ~typing.Any = <class 'numpy.float32'>) → None¶

static update_static_buffer_data(new_data: ndarray, vbo: Buffer, resize_target: int) → None¶

static depth_test_if_enabled(ctx: mgl.Context, item: Item)¶

class janim.render.base.RenderData(*, ctx: Context, camera_info: CameraInfo, light_source_location: ndarray, anti_alias_radius: float)¶

基类：object

在渲染过程中需要配置的属性

通过 Renderer.data_ctx 进行设置和获取

ctx: Context¶

camera_info: CameraInfo¶

light_source_location: ndarray¶

anti_alias_radius: float¶

janim.render.base.apply_blend_flags(ctx: Context) → None¶

janim.render.base.create_context(**kwargs) → Context¶

janim.render.base.create_context_430_or_330(**kwargs) → Context¶
