A little comparison of the V-Ray fur system used on Spinmaster’s Paw Patrol Season 2 to create procedural grass throughout the show. Written in Python and leveraged the power of Maya, Nuke and Shotgun to power the creation process.

PyQt DirCompleter

Sometimes you know exactly what you want to build but just have no idea what blocks to use when you start building. When I first looked into replicating the shell experience of stepping through directories it took me a while to track down the right PyQt modules. My first attempts were very complex, so when I discovered how simple the final product was I really couldn’t believe it.

#!/usr/bin/env python import sys from PyQt4 import Qt, QtCore, QtGui import os """ This is a simple example of how to use PyQt's completer with a directory model As you type, the completer finishes off you search with the files in the directory """ class DirModel(QtGui.QWidget): def __init__(self): super(DirModel, self).__init__() self.initUI() def initUI(self): # ---- Title & Line edit self.input_file_title = QtGui.QLabel('Your dir model completer') self.input_file_line = QtGui.QLineEdit() # ========================================== # ---- COMPLETER dir_model = QtGui.QDirModel() self.input_line_completer = QtGui.QCompleter() self.input_line_completer.setModel(dir_model) self.input_file_line.setCompleter(self.input_line_completer) # ============================================== # ---- Fill in your input path with the directory you ran the script from current_dir = os.getcwd() self.input_file_line.setText(current_dir) # ---- Build Layout vbox = QtGui.QVBoxLayout() hbox_input_file = QtGui.QHBoxLayout() hbox_input_file.addWidget(self.input_file_title) hbox_input_file.addWidget(self.input_file_line) vbox.addLayout(hbox_input_file) self.setLayout(vbox) self.resize(400, 100) self.setWindowTitle('PyQt Dir Completer') self.show() def main(): app = QtGui.QApplication(sys.argv) mt = DirModel() sys.exit(app.exec_()) if __name__ == "__main__": main()

Maya Camera Cull

This is a simple script written in python for Maya. It will select the geometry seen through the specified camera and return either the name of the objects or the component information (face or vertex info).

First Blog Post!

Hello everyone! This is something I’ve meant to do for a long time and finally the day is here. I have created this website to post work, work-in-progress and anything cool and interesting I have learned along the way. I know how many of these personal blogs have helped me out in the past and here is to hoping I can help someone out in the future.

Hope you enjoy!
