TV3D 6.5 and C++ Questions

[microdot]

Hi Guys 

I have two questions. 1) I have loaded a heightmap but textures are not showing and 2) My input code is dodge. I cannot intercept mouse input and my heightmap vanishes after about 50deg in either direction when I rotate using keys A and D.

Here is code:

Issue 1:

Code:

pScene->SetViewFrustum(60,5000);
pScene->SetTextureFilter(cTV_FILTER_TRILINEAR);

pLighting = new CTVLightEngine();
pLighting->SetGlobalAmbient(0,0,0);

pTextureFactory = new CTVTextureFactory();
int Texture = pTextureFactory->LoadTexture("K:\\text.bmp", "landText", 2048, 2048);

pLandscape = new CTVLandscape();

pLandscape = pScene->CreateLandscape("landMap");

pLandscape->GenerateTerrain("K:\\height.bmp", cTV_PRECISION_HIGH, 8, 8, 0, 0, 0,true);
pLandscape->SetLightingMode(cTV_LIGHTING_MANAGED);
pLandscape->ExpandTexture(Texture, 0, 0, 8, 8,true);
    pLandscape->SetCullMode(cTV_BACK_CULL);

PosSx = 1024;
PosSy = 0;
PosSz = 1024;

PosX = 0;
PosY = 100;
PosZ = 0;

    pScene->SetCamera(0, 100, 0, 1024, 0, 1024);
pCamera = pScene->GetCamera();


cTV_3DVECTOR* x = new cTV_3DVECTOR(-1,-1,1);
Sun = pLighting->CreateDirectionalLight(x, 1,1,1,"sunlight",1);
pLighting->SetSpecularLighting(true);

pMaterial = new CTVMaterialFactory();
LandMat = pMaterial->CreateMaterial("landMat");

pMaterial->SetAmbient(LandMat, 0.1f,0.1f,0.1f,1);
pMaterial->SetDiffuse(LandMat, 0.8f,0.8f,0.8f,1);
pMaterial->SetSpecular(LandMat, 0.2f,0.2f,0.2f,1);
pMaterial->SetPower(LandMat, 20);
pMaterial->SetEmissive(LandMat, 0,0,0,1);

pLandscape->SetMaterial(LandMat, -1);

In my render loop -

Code:

pLighting->EnableLight(Sun, true);
pLandscape->Render();

Issue 2:

Code:

void KeyPressCheck()
{
pScene->SetCamera(PosX, PosY, PosZ, (float)(PosX + pMath->ACos(Ang)), (float)(PosY + pMath->ASin(AngY)), (float)(PosZ + pMath->ASin(Ang)));


if (pInput->IsKeyPressed(cTV_KEY_A))
{     
Ang = Ang + pTV->AccurateTimeElapsed()  * 0.001f;
}
if (pInput->IsKeyPressed(cTV_KEY_D))
{
Ang = Ang - pTV->AccurateTimeElapsed()  * 0.001f;
}

PosX = PosSx;
            PosY = PosSy;
            PosZ = PosSz;

Any help appreciated.

Anyone?

You sure you have set the texture to landscape, currently you are only expanding one. Try Landscape.setTexture after generation.

Thanks for the advice.

I did try pLanscape->setTexture(texture number, -1); after the heightmap was created. Still grey. I checked log files too, texture is loaded correctly.

Does my second issue, input control look correct? I seem to lose the level at about 50degrees any direction, like the camera doesn't know the level is there anymore. Even tried turning culling off just to test.

Code:

void KeyPressCheck()
{


if (pInput->IsKeyPressed(cTV_KEY_A))
{     
Ang = Ang + pTV->AccurateTimeElapsed()  * 0.001f;
}
if (pInput->IsKeyPressed(cTV_KEY_D))
{
Ang = Ang - pTV->AccurateTimeElapsed()  * 0.001f;
}

PosX = PosSx;
            PosY = PosSy;
            PosZ = PosSz;

pScene->SetCamera(PosX, PosY, PosZ, (float)(PosX + pMath->ACos(Ang)), (float)(PosY + pMath->ASin(AngY)), (float)(PosZ + pMath->ASin(Ang)));

I think you have to call SetCamera after checking keys, not before.

If I call the set on camera after keyboard processing, when I exit the app protected memory is written to and the app crashes.

Also I had no luck with different results level still goes away when rotating.

Do you have a keyboard and mouse example in C++ for me to compare against?

Yeah there's TONS of samples in this forum who have this. first thing I meeted on forums now is http://www.truevision3d.com/forums/tv3d_sdk_65/zaks_hlsl_sky_demo_in_vbnet_download-t12366.0.html
All Zak's samples/shaders/demos use good input management.

That is exactly what I was looking for, If you reckon implementation was good I will use the opportunity to learn from it.

Anyone have ideas on what I did incorrectly with my terrain that took away my texture that was loaded? Debug file says loaded fine, code expands from points 0,0 to heights 8,8 as setup. I have tried setTexture too.

Did my lighting implementation mess it up? I had to add a material to the landscape for lighting to work. Perhaps this is my issue.

Appreciate the help on all this so far.
