This approach does an expensive computation each time, even under error conditions. A way to avoid this would be to say:

Suppose that we use a lot of B class objects in a program. Each object must be constructed, but we know that the constructor function body is empty. So will there be a performance issue?

In performance tips this issue, we will present a complete C++ class along with its implementation code, which is appended to the end of the discussion.

In this tutorial we will present some practical performance tips for improving code speed and reducing memory usage. Some of these tips will be useful only for C++ code and some will be more general and applicable to C or other languages.

Suppose that you wish to output three values and you use some C-style output to do so:

Imagine that you want to devise a way to represent calendar dates for use in a C program. In this tutorial you will learn it all.

Many of the techniques used in writing robust C code also apply in C++. For example, if you have a function that is supposed to be passed a person's name, as a C-style string, it would be wise to say:

This tutorial was designed to teach anyone who is interested in rendering with Mental Ray's Final Gather but was either scared to learn or simply didn't think they had the time. Well, I hope this tutorial can quiet your fears and answer some questions. The information i'm about to share with you is by no means original. Yes, I created all the images and renderings, however I am only offering you...

In this tutorial i will try to teach you how to make realistic clouds in maya software. I hope you will enjoy it.

The Uninstancer allows you to bake particle instances into geometry, animation, and blendshapes that can be modified and updated without messing around with dynamics and expressions.

What I'm going to do is try and show you the main steps of how I made my "Male Green Frog" image. I used Maya 8 for modelling, MentalRay for rendering and Photoshop for the textures.

During a recent travel, I'd taken a photo at the “Bird Park” of Kuala Lumpur. Immediately I was captured by the expression of this parrot….a strange mixture of drama, given from the animal in the cage, and of fun as demonstrated by the typical behavior of these animals.

Photography has always inspired me; I love especially shots of nature and wildlife from magazines like The National Geographic. During a recent travel in the South East of Asia, I visited Sriracha Tiger Zoo in Thailand and I took many photos of all the animals living there. There is no better reference material to use than the one you personally create wink

Photography has always inspired me, especially shots of nature and wildlife from the National Geographic magazines. I decided to use the American alligator as the subject for my project, perhaps because I’ve always been fascinated by reptiles (this species in particular has truly brilliant colors) and I really wanted to enjoy the modeling process.

I would like to share my method on rendering z-depth images. In this tutorial you will learn to render z-depth image directly in the renderview in an easy and fast manner.
