Have no idea,
When it's done lol

I have a lumia 1020, can't wait to test it pfft

Hi,

The requirements for Windows Phone will be Windows 10 + GPU with DX10/11 Feature Level 9_3 or better.

Based on this website https://en.wikipedia.org/wiki/Nokia_Lumia_1020 it looks like you have Adreno 225.
And based on this website https://en.wikipedia.org/wiki/Adreno I'm not sure if your GPU meets the DirectX Feature Level requirements.
However this website http://www.anandtech.com/show/4940/qualc...itecture/3 says otherwise, so you'll have to see it yourself.

And another screen from today's progress grin

3D now fully available :>

Actually this is not glow wink

It's specially crafted textures + glow-like particle effects.
This gives very good performance on mobile, compared to a full post process shader.

Hi,

It's very simple, just draw a single particle:

You can use code similar to that:

Code:

class Glow

{

   static ImagePtr image;

   static Color    color(255, 192, 64);

   static flt      radius=0.4;

   static void Init()

   {

      image=UID(3007031556, 1137099648, 934413987, 3085159623);

   }

   static void Begin()

   {

      DrawParticleBegin(*Glow.image, 0, false);

   }

   static bool Test(C Vec &pos)

   {

      return Frustum(Ball(radius, pos));

   }

   static void Add(C Vec &pos, flt power)

   {

      Vec p=pos, delta=p-Cam.matrix.pos; flt d=delta.normalize(); p-=delta*(radius*0.5);

      d/=D.viewRange(); d=1-Cube(Sqr(d));

      DrawParticleAdd(color, power*d, radius, 0, p, VecZero);

   }

   static void End()

   {

      DrawParticleEnd();

   }

   Vec pos=VecZero;

   flt power=0.35;

   void draw()

   {

      if(Test(pos))Add(pos, power);

   }

   // io

   bool save(File &f)C

   {

      f.cmpUIntV(0);

      f<<pos<<power;

      return f.ok();

   }

   bool load(File &f)

   {

      switch(f.decUIntV())

      {

         case 0:

         {

            f>>pos>>power;

            if(f.ok())return true;

         }break;

      }

      return false;

   }

}

Memc<Glow> Glows;

void Render()

{

   switch(Renderer())

   {

      case RM_BLEND:

      {

         if(Glows.elms())

         {

            Glow.Begin();

            FREPAO(Glows).draw();

            Glow.End();

         }

      }break;

   }

}

All major issues have been fixed!
I need to do last bit of testing, and I will release the new engine update within a couple days smile

Tottel · 03-09-2016 11:05 AM

Yayyy! Nice work, Esenthel. smile

Can't wait to try out all that new stuf!

Universal Windows Platform support is fully functional, as my game Dungeon Hero got accepted to Windows Store for Desktop and Phones:

UWP apps now on Xbox too smile

**Esenthel** · 03-31-2016 09:59 AM

Thanks for sharing, looks like I've added UWP support in right moment grin

Is this sufficient for Hololens development?

My understanding is that Hololens applications are Universal Apps but I'm a bit vague on whether there is need for extensions specific to the device.

**Esenthel** · 06-04-2016 12:39 AM

Hi,

I have no idea, but my guess is that it'll work.
Although the idea for Hololens is to draw 3D on top of existing things that you see, so probably you'd have to add some extra work on the source code for that, and also to detect device input sensors.
