Streaming World – Part 3

With all the major parts in place, next steps are all about improving overall appearance and boosting performance. I will tackle performance in the next and final part of this series. For now, let’s take a quick look at adding some visual appeal.

My first job is to improve texturing. All the screenshots you’ve seen so far have just been a flat grass texture. I implemented a basic simplex noise setup to create tiled patterns like below.


I then used marching squares to handle tile transitions from water > dirt > grass > stone. Daggerfall actually has a wider range of possible transitions (e.g. water > grass) but for simplicity I’ve only implemented the basic transitions so far. With marching squares the transitions look like this.


I also added a little fog so distant terrain gradually blends into horizon. This gives the atmosphere a greater feeling of depth at long ranges like you would see in the real world.

The final step was to add nature flats (vegetation, rocks, etc.) to scene. This is just a basic random function with a density set per tile type. This could be expanded later to change vegetation density based on any number of variables. Finally, we have a world that almost looks ready to explore.

There’s still a great deal of work to go before this is ready. Due to the rapid nature of development, nothing has been optimised yet and performance is very poor. My first priority is a full performance review of the entire tools to get this where it needs to be. Everything from loading textures and models all the way up to drawing terrain and foliage needs to be improved. This will unfortunately delay the streaming world features until early next year, but the end result will be a much improved code base.

Another, smaller item will be the overall scale of terrain and distribution of vegetation. If you look at the coastal Sentinel screenshot above, the terrain ramps up much too rapidly. I need to set terrain scale based on biome (e.g. desert is flatter than mountains), and terrain noise based on biome (e.g. desert is more rolling than mountains). This is just a matter of tuning the numbers going into terrain generation for an overall more pleasing game space.

On the whole, I’m very happy with how the streaming world is shaping up. It’s basically where I want it in terms of recreating Daggerfall’s simplistic overworld, and just needs performance and aesthetic tuning. I can’t wait to get all of this completed so you have a whole world to build on using Daggerfall Tools for Unity.

This will be my final post for the year. I’m shutting down work at the end of this week and will be spending valuable time with family. I wish you all a very happy and safe Christmas and look forward to catching up again in the New Year.

  1. That looks really awsome, better than Daggerfall itselfe!
    I’m reallly looking forward to the next release 😉

    Happy Holidays and Happy New Year 😉 ! Cant wait to hear from you 2015 😀

  2. Those are some lovely screenshots! 😀 I’ve been meaning to check out your work in the Oculus Rift, but I’ve been separated from my desktop PC so much I haven’t been able to yet. But once that opportunity presents itself it looks like I’ll have a lot to check out. I’m really happy to see you able to continue your work. Have a great holiday season, and thank you for continuing to breathe life into Daggerfall! 😀

  3. These look very good man :)….I’m really looking forward to see this in motion.

    But for now,after all the progress you did this year, take a break man! You deserve it (seriously).
    Don’t go too harsh on yourself :). I wish you Happy Holydays! Hope you have a great time with the ones you love!

    See you in 2015 mate !
