Submodules

fruitloop.utils.gl module

class BindNoTargetMixin

Bases: fruitloop.utils.gl.BindTargetMixin

Same as BindTargetMixin, but for bind functions that don’t have a specified target.

bind()

classmethod unbind()

class BindTargetMixin

Bases: object

Mixin that speifices a bind() and unbind() interface by taking advantage of the OpenGL bind format: bind: bindfun(target, id) unbind: bindfun(target, 0)

bind()

bindfun = None

classmethod unbind()

class BindingContextMixin

Bases: object

Mixin that calls self.bind() and self.unbind() when used in a context manager.

class ElementArrayBuffer(*args, **kwargs)

Bases: fruitloop.utils.gl.VBO

target

class GlGenMixin(*args, **kwargs)

Bases: object

genfun = None

class VAO(indices=None, **kwargs)

Bases: fruitloop.utils.gl.GlGenMixin, fruitloop.utils.gl.BindingContextMixin, fruitloop.utils.gl.BindNoTargetMixin

OpenGL Vertex Array Object. Sends array data in a Vertex Buffer to the GPU. This data can be accessed in the vertex shader using the ‘layout(location = N)’ header line, where N = the index of the array given the VAO.

Example: VAO(vertices, normals, texcoords):

Fragshader: layout(location = 0) in vec3 vertexCoord; layout(location = 1) in vec2 texCoord; layout(location = 2) in vec3 normalCoord;

assign_vertex_attrib_location(vbo, location)

Load data into a vbo

bindfun

draw(mode=<Mock id='140636315753808'>)

element_array_buffer

genfun

class VBO(ndarray, *args, **kwargs)

Bases: fruitloop.utils.gl.GlGenMixin, fruitloop.utils.gl.BindingContextMixin, fruitloop.utils.gl.BindTargetMixin

bindfun

genfun

target

create_opengl_object(gl_gen_function, n=1)

Returns int pointing to an OpenGL texture

enable_states(*args, **kwds)

Context Manager that calls glEnable and glDisable on a list of gl states.

setpriority(pid=None, priority=1)

Set The Priority of a Windows Process. Priority is a value between 0-5 where 2 is normal priority. Default sets the priority of the current python process but can take any valid process ID.

vec(floatlist, newtype='float')

Makes GLfloat or GLuint vector containing float or uint args. By default, newtype is ‘float’, but can be set to ‘int’ to make uint list.

fruitloop.utils.orienting module

calculate_model_matrix(position, rotation, scale)

Returns 4x4 model matrix from the (x.y,z) position and XYZ Euler rotation, in degrees.

calculate_view_matrix(position, rotation)

TReturns 4x4 view matrix from the (x.y,z) position and XYZ Euler rotation, in degrees.

fruitloop.utils.timers module

countdown_timer(total_secs, stop_iteration=False)

Generates an iterator that returns the time remaining from total_time (secs). Returns 0.0 when time is up, unless stop_iteration is True.

dt_timer()

A Generator that returns the time since last called. Never returns StopIteration.
