Warp Speed...

[yodathegreat]

Hi all,


I will like to simulate a WARP Speed, you see ?

The same effect that in Startrek when the ships is in Warp Speed.

I want the Star trace..

I have try why Particle, but I don't have trace "remanance"...

Best regards

The last effect is done with gl_line. I don't see draw3dline having support for two colours, but maybe you can do a direct call to opengl functions? Does anyone know if this is possible?

Edit:
I thought I posted the code, but anyway, here it is:

Code: Select all

typedef struct {
	float x;
	float y;
	float z;
	float speed;
} WarpStar;
---

		glRotatef(rotates,0.0f,0.0f,1.0f);
		glTranslatef(-50.0f,-50.0f,-100.0f);
		glBegin(GL_LINES);
		    for(int i = 0; i < 600; i++)
			{
				glColor3f(0.3f,0.3f,1.0f); glVertex3f(wstar[i].x,wstar[i].y,wstar[i].z);
				glColor3f(1.0f,1.0f,1.0f); glVertex3f(wstar[i].x+0.1f,wstar[i].y,wstar[i].z+4.0f);
			}
		glEnd();

		for(int i = 0; i < 1000; i++)
		{
			wstar[i].z += wstar[i].speed*demo.speed;
			if(wstar[i].z >= 100.0f) wstar[i].z = -1.0f;
		}

one way you could do it would be to make a 3-4 second animation of it in a program like 3dsmax or lightwave , cache it , then call it almost like a cut scene with the exception being to set the animation "invisible " and have it looping in the background , then when you want to display it make it visible again with setVisible()

Hi,

Thank you for you code
But I don't have the fonctions "glRotatef" "glColor3f" "glBegin" etc

I use only DirectX, OpenGl is slow.

Yes. OpenGL is slow in irrlicht, but I'm sure that there are similar functions in DX to the ones shown in the code, so it should be rather easy to create a DX version.
