[0:19][A regrettable incident...]
[6:07][Maybe we should try to add some sort of drawing to the ground]
[7:13][Viewing the art assets in GIMP]
[11:12][Casey's vision for the art]
[15:10][Load ground textures]
[17:32][Introduce DrawTestGround to composite the textures]
[21:16][Viewing the results in-game]
[21:45][Randomly splat down a ton of grass textures]
[23:16][Looking at RandomNumberTable]
[24:42][Figure out the maximum value of RandomNumberTable]
[26:41][...and the minimum value]
[28:11][Produce a floating point number between 0 - 1 within the range of RandomNumberTable]
[29:44][Blackboard: Transforming a number from being between 0 - 1 to between -1 - 1]
[34:05][Blackboard: What happens in between two points?]
[37:26][Blackboard: Degrees of polynomial]
[45:29][Implement the equation f(x)=2x-1 and splat multiple grass textures]
[47:43][Account for the centre of the bitmap]
[49:18][Set the radius by which to offset the splats]
[51:05][Provide a function to make a v2 out of integers]
[53:17][Parameterise loaded_bitmap]
[58:10][Restart the game]
[58:30][Tuft it up][quote 42]
[59:36][Q&A][:speech]
[1:00:29][On the fancy autoload dll stuff]
[1:01:52][Q: Is there an art team working on this game?]
[1:02:41][@mmozeiko][Max random number should be set to fixed number 100000\[...\] because in episode 35 when you went to random.org you chose to generate random numbers from 0 up to that number]
[1:03:51][@pseudonym73][Obviously that wasn't a serious comment. But on-topic question: Do you want to mention tangents when designing curves?]
[1:04:40][@panic00][Would you ever actually use a higher degree polynomial interpolation? Aren't there better ways to make interpolating curves that are more stable?]
[1:13:53][Q: What sort of optimisation would you do on that ground stamping?]
[1:16:16][Q: You aren't treating both ends of the random numbers the same. With the current system you can get 1 but you will never get 0 because you are not considering the min...]
[1:18:29][Q: Do you plan on having things like dirt paths and, if so, would you draw them using splats and stamps?]
[1:20:08][Q: So your ground texture design is essentially MegaTexture?]
[1:21:09][Q: Based on the stream, it appears that you need to know math to do this type of activity. Is that correct?]
[1:22:13][Blackboard: Casey's Plan vs. MegaTexture]
[1:32:47][Q: Why do you think John Carmack is a hack and when are you going to say it to his face?]
[1:36:06][Conclusion][:speech]
