hxsl's Issues

Cannot merge back :)

Because haxelib's format is not up to sync for format.agal...

Can you please release a new format version ?

thx

Allow store in Bool params null/true/false

Now boolean params can't contains null value

why not m33 ,now it is dp3

Test2.hx:20: vertex:
mov t0.xyz, c4.xxx
dp3 t1.x, t0.xyz, c0
dp3 t1.y, t0.xyz, c1
dp3 t1.z, t0.xyz, c2
mov out, t1.xyzz
fragment:
mov out, c0.xxxx

[feature] shader from 'puzzle'

Something like https://github.com/andyli/puzzle
very usefull thing for lights, post effects, etc

separate init methods for vertex and fragment shader

Very useful for batch, then one texture and one one shader render many times.

Problem with array M44<20>

In hxsl 1 this shader worked ok, now strange problem

class Batch2DShader extends Shader
{
    static var SRC = {
        var input : {
            pos : Float2,
            uv: Float2,
            index:Float
        };

        var tuv:Float2;
        var cTrans:Float4;
        var pWrap:Param<Bool>;
        var pFilter:Param<Bool>;
        var pMipmap:Param<Bool>;

        function vertex(mproj:Matrix, mpos:M44<20>, cTransArr:Float4<20>, regions:Float4<20>)
        {
            // http://code.google.com/p/hxformat/issues/detail?id=28#c8
            //var i = input.pos.xyzw;
            //i.x = input.index.x * 4;
            //out = input.pos.xyzw * mpos[i.x] * mproj;
            out = input.pos.xyzw * mpos[input.index * 4] * mproj;

            var region = regions[input.index];
            tuv = input.uv * region.zw + region.xy;
            cTrans = cTransArr[input.index];
        }

        function fragment(tex:Texture)
        {
            out = tex.get(tuv, wrap=pWrap, filter=pFilter, mipmap=pMipmap) * cTrans;
        }
    };
}

3.2 rc-2 with static analyzer gives RuntimeCompiler error

I try to compile a Flambe project using the new -D analyzer, but I now get this error:

C:\HaxeToolkit\haxe\lib\hxsl/2,0,3/hxsl/RuntimeCompiler.hx:573: characters 17-20 : Unbound variable _g

Not sure if this is a Haxe or HXSL error.

Compilation error

I trying to compile HxSL with latest nightly version of 3.1.0 compiler and got an error:

 /Users/fomkin/repos/thirdparty/hxsl/src/main/haxe/hxsl/Shader.hx:95: characters 11-12 : Unmatched patterns: TArray(_,_)

Shader.unbind doesn't unbind textures

In the file Shader.hx in the method unbind on line 321 at says:

ctx.setTextureAt(k, i.textures[k]);

After modify that line to:

ctx.setTextureAt(k, null);

the method unbind works as expected.

multiple texture usage in hxsl

I write fragment func like this
function fragment(tex0:Texture, tex1:Texture, tex2:Texture, tex3:Texture)

but the problem is I don't the exact number of textures will used here

currently I uploaded 8 tex with some empty bitmapdata textures

but in agal I can dynamically make the agal opcode string to achieve this
for (var x:int;i < textureCount;i++){
"tex " + ftColor + "," + + "," + fsList[i] + "<2d,repeat,miplinear,linear>",
}

The thing I wanna achieve is similar like this:

Matrix multiplication (+ small Camera problem)

Hi,
Here a big and a small problem.
The big one is about matrix multiplication.
To make an application targeting AS3, I took the example 2_texture as a base. As I wanted the projection matrix to affect the direction of the light (It was a mistake, but it doesn't matter here), so I replaced:
function vertex( mpos : M44, mproj : M44, light : Float3 ) {
out = input.pos.xyzw * mpos * mproj;
var tnorm = (input.norm * mpos).normalize();
lpow = light.dot(tnorm).max(0);
tuv = input.uv;
}
by
function vertex( mpos : M44, mproj : M44, light : Float3 ) {
out = input.pos.xyzw * mpos * mproj;
var tnorm = (input.norm * mpos * mproj).normalize();
lpow = light.dot(tnorm).max(0);
tuv = input.uv;
}
then I wanted to optimize by putting mpos_mproj in an variable, so I changed it for:
function vertex( mpos : M44, mproj : M44, light : Float3 ) {
var mposproj:M44 = mpos_mproj;
out = input.pos.xyzw * mposproj;
var tnorm = (input.norm * mposproj).normalize();
lpow = light.dot(tnorm).max(0);
tuv = input.uv;
}
and got an error on mpos_mproj:
M44 should be M44
I changed mposproj declaration for:
var mposproj = mpos_mproj;
and then got an error on input.pos.xyzw * mposproj:
M44 should be Float4

The small problem come with the Camera class that is given with the examples.
As the X,Y,Z vectors in Stage3D form a left-hand frame (see http://www.adobe.com/devnet/flashplayer/articles/3d-cameras.html) with X axis to right, Y to up and Z to front, the resulting projection matrix of Camera class comes reversing bottom and up.
In my case, I solved the problem replacing line 44:
var ay = az.cross(ax);
by
var ay = ax.cross(az);
It solved the problem with AS3 but it could cause it for other platforms. Maybe a better solution could be fine using precompilation instructions.

Reassing realType

Now realtypes are fixed in Build.hx

Will be great call something

Build.setRealType(TFloat3, "my.math.Float3");

hi, ncannasse

Cannot compile the code.

You can provide h3d and hxsl under the haxe2.10 version?

}

output

Publish to haxelib

It would be great if HXSL was available on haxelib, so that it can be specified as a dependency.

Unmatched patterns: TArray(_,_)

Should be an easy fix, when using latest Haxe: Shader.hx:95: characters 11-12 : Unmatched patterns: TArray(_,_)

pls add ShaderInstance vertexnamemap

I see the vertexmap.like 0 16 32
but the 0 name?
thanks.

It does not seem tow ork with haxe3?

I just downloaded the lib and the samples, and I cannot compile them,. Is it that this is not compatible with H3?

error in max constants determination

Build.hx file (line 117)

if( vcount >> 2 >= format.agal.Tools.getProps(RConst, !shader.vertex).count )

Must be:

if( vcount >> 2 > format.agal.Tools.getProps(RConst, !shader.vertex).count )

We have 128 registers, not 127.

texture flags as parameters

Something like

var uv:Float2;

function fragment(data:TextureFlags, tex:Texture2D)
{
  out = tex.get(uv, data);
}

If / Float / Bool problem

Hi,

I noticed a Float/Bool conversion problem while trying to test an expression such as:
if ( xxx > 0.5) doSomething;
xxx being a Float

Compiler gives: "Float should be Bool" for the expression "xxx > 0.5"

The problem is that comparison operations between Float return a Float which value is 0 or 1 but if test requires a Bool and there is no conversion.

It seems to occurs in Compiler.hx when on line 206 is called "unify(cond.t, TBool, e.p);"
unify calls tryUnify which throws that error.

I also noticed that expressions such as if (aConstant == null) or if (aConstant!=null) do compile as they seem to return a Bool.

I presume that that exception is linked with the lines 801-817 of Compiler.hx, in the makeOp method.
That block starts with the comment: // if we have a null check, infer a VParam

On line 76, I tried to replace:
case CMin, CMax, CLt, CGte, CEq, CNeq, CLte, CGt: floats;
By:
case CMin, CMax: floats;
case CLt, CGte, CEq, CNeq, CLte, CGt: [ { p1 : TFloat4, p2 : TFloat4, r : TFloat4}, { p1 : TFloat3, p2 : TFloat3, r : TFloat3}, { p1 : TFloat2, p2 : TFloat2, r : TFloat2} , { p1 : TFloat, p2 : TFloat, r : TBool } ];
My shader compiled but failed at runtime.

I also tried to put in tryUnify, after the line 740:
case TFloat: return (t2 == TFloat || t2 == TBool);
but I had the same result. It compiled but failed at runtime.

Thank you for your work,
Olivier.

why not more than 32 param?i have a shader need more

if( paramCount == 32 )
Context.error("Too many runtime parameters for this shader (max=32)", v.pos);

Unknown identifier : VParam

I've got this when I try to run samples:

C:\Motion-Twin\Haxe\lib\hxsl/2,0/hxsl/Shader.hx:145: characters 17-23 : Unknown identifier : VParam

When I change:

Shader.hx line 26

from: import hxsl.Data.Tools;

to: import hxsl.Data;

samples worked.

What is my problem?

Recent hxformat release breaks hxsl

/home/bruno/.haxe/lib/hxsl/2,0,3/hxsl/AgalCompiler.hx:178: lines 178-181 : Object requires field version
/home/bruno/.haxe/lib/hxsl/2,0,3/hxsl/AgalCompiler.hx:120: lines 120-182 : Missing return format.agal.Data

This breaks new Flambe installs and anything else that depends on hxsl. :(

Do you think you could explicitly specify the dependency version in haxelib.json to prevent this from happening again in the future?

Build.hx small speedup

I got little speed up in Builder.hx in buildShaderInfos method. I introduced local variables like here

https://github.com/profelis/dd/blob/master/dd/src/hxsl/Build.hx#L72

or here

https://github.com/profelis/dd/blob/master/dd/src/hxsl/Build.hx#L105

In my stress test I got 48-49 fps versus old 45 fps.

Btw, getVertexConstants and getFragmentConstants can be inlined for small speedup too

m44[1]

class TestShader extends Shader {
var SRC = {
var matr:M44;
function vertex() {
out = [1, 1, 1, 1]*matr[0];
}

    function fragment() {
        out = [1,1,1,1];
    }
};

}

PicoShader multiple compilation errors

class PicoBuild {
macro public
// remove @ before macro

var decls = ["override function getData() return '"+s+"';",];
// add ";" at end

at PicoShaderInstance
for ( v in data.vars ) {
// replace with
var allVars = Tools.getAllVars(data);
for ( v in allVars ) {

Looks like Pico*-branch not supported?

bind multi vertexbuffer instance

It seems I have to combine all vertexbuffer to one,and call shader.bind(buf)?

How I wish I could do this:
shader.bind(buf1,buf2,buf3)...
