The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Having a problem getting data from .obj file to render (index / Vertex buffer prob)

5 posts in this topic

I've tried everything I could think of, every possible thing and yet, I can't get the .obj mesh to render. It gets all the vertices and indices (I think.) But when I try to pass it on to DIrect3D9's vertex and index buffers, it.....doesn't go well. Here's a few links and my explanation.

 

meshobj.cpp file:

 

(note: to keep this post short, I'll be using pastbin for code.)

mesh.obj file:

and finally: a screen shot of what PIX shows.....

as you can see, the vertices don't seem to be pushed through the pipeline right...I've given all I can give to explain this problem. If you could help me out, I'd appreciate it. let me know if you need to see something else.

just wondering, are you multiplying with the world matrix twice? in pix it shows the world transform twice

 

i haven't used directx 9 forever, but what happens when you comment out the line: 

 

this->Transform();

Also, check my dx9 c++ obj loader sample if you'd like: click

 

That helps a bit, but why use FVFs? I've noticed .X files (deprecated, yes), use vertex declarations (without loading effects). So it's possible to use vert decl without shaders, no?

You can map FVFs to vertex declarations. In fact, if I'm not mistaken, directx will internally do that if you stick with FVFs. Also, you can use vertex declarations with the fixed function pipeline (but why would you use the fixed function pipeline and not shaders?). See the section "Vertex Declaration Usage with the Fixed Function Pipeline" here.
