pyunity.render module

Classes to aid in rendering in a Scene.

pyunity.render.gen_buffers(mesh)

Create buffers for a mesh.

Parameters:mesh (Mesh) – Mesh to create buffers for Returns:Tuple containing a vertex buffer object and an index buffer object. Return type:tuple

pyunity.render.gen_array()

Generate a vertex array object.

Returns:A vertex buffer object of floats. Has 3 elements:

# vertex    # normal    # texcoord
x, y, z,    a, b, c,    u, v

Return type:Any

class pyunity.render.Shader(vertex, frag, name)

Bases: object

compile()

Compiles shader and generates program. Checks for errors.

Notes

This function will not work if there is no active framebuffer.

static fromFolder(path, name)

Create a Shader from a folder. It must contain vertex.glsl and fragment.glsl.

Parameters:

• path (str) – Path of folder to load
• name (str) – Name to register this shader to. Used with Camera.SetShader.

setVec3(var, val)

Set a vec3 uniform variable.

Parameters:

• var (bytes) – Variable name
• val (Any) – Value of uniform variable

setMat4(var, val)

Set a mat4 uniform variable.

Parameters:

• var (bytes) – Variable name
• val (Any) – Value of uniform variable

setInt(var, val)

Set an int uniform variable.

Parameters:

• var (bytes) – Variable name
• val (Any) – Value of uniform variable

setFloat(var, val)

Set a float uniform variable.

Parameters:

• var (bytes) – Variable name
• val (Any) – Value of uniform variable

use()

Compile shader if it isn’t compiled, and load it into OpenGL.

pyunity.render.compile_shaders()

class pyunity.render.Camera(transform)

Bases: pyunity.core.SingleComponent

Component to hold data about the camera in a scene.

near

Distance of the near plane in the camera frustrum. Defaults to 0.05.

Type:float

far

Distance of the far plane in the camera frustrum. Defaults to 100.

Type:float

clearColor

The clear color of the camera. Defaults to (0, 0, 0).

Type:RGB

setup_buffers()

Creates 2D quad VBO and VAO for GUI.

fov

FOV of camera

orthoSize

Resize(width, height)

Resizes the viewport on screen size change.

Parameters:

• width (int) – Width of new window
• height (int) – Height of new window

getMatrix(transform)

Generates model matrix from transform.

get2DMatrix(rectTransform)

Generates model matrix from RectTransform.

getViewMat()

Generates view matrix from Transform of camera.

UseShader(name)

Sets current shader from name.

Render(renderers, lights)

Render specific renderers, taking into account light positions.

Parameters:

• renderers (List[MeshRenderer]) – Which meshes to render
• lights (List[Light]) – Lights to load into shader

Render2D(canvases)

Render all Image2D and Text components in specified canvases.

Parameters:canvases (List[Canvas]) – Canvases to process. All processed GameObjects are cached to prevent duplicate rendering.

class pyunity.render.Screen
